INTRODUCTION1 INTRODUCTION1.1 System OverviewThe SeaBat 7101 is a high-resolution multibeam sonar system operating at 240kHz thatmeasures relative water depths over a 150° wide swath perpendicular to the vessel'strack.The SeaBat 7101 is designed for installation on the hull of a surface vessel, ROV, ortowed body, and is available in depth ratings up to 3000 meters.The SeaBat 7101 is available as a complete system or as an upgrade to existing SeaBat8101 systems.Figure 1: SeaBat 7101 Sonar System1.2 System ArchitectureThe SeaBat 7101 multibeam sonar system consists of the 7-P-1 Sonar Processor Unit(SPU) and a combined projector and receiver unit known as the sonar head. A singlecable connects the sonar head to the SPU. User displays and system control originatewithin the SPU.SeaBat 7101 Operator’s Manual Page 1 January 15, 2009Version 1F

INTRODUCTIONFigure 2: SeaBat 7101 System Configuration1.3 System OperationThe projector section of the sonar head transmits a pulse of acoustic energy, whichtravels through the water medium and is reflected by the seafloor or any objects in itspath. The reflected signal is received by the receiver section of the sonar head, digitizedby internal electronics, sent to the topside sonar processor unit (SPU) for beamformingand processing. The SPU generates the video displayed on the monitor and formats adigital output to be used by a peripheral bathymetric data processing system whilefunctioning as the control interface between the operator and the sonar system.1.4 System FeaturesThe main features of the SeaBat 7101 system are summarized below:• Resolution: Dynamic, focused beamforming maintains ultra-high resolution,even at short ranges. A receiver sample rate of 15ksps providesunprecedented range resolution and complements the narrow beam, thusproviding the user with ultimate data quality and resolution.• Fast Update: The entire 150° swath is illuminated with a single transmissionat an update rate of up to 40Hz (range selection dependent), maintaining100% bottom coverage, even at high speed.• Depth Rating: The SeaBat 7101 is depth-rated to 100 or 120 meters withoptional 1500 or 3000 meter depth rating.• Data Output: The SeaBat 7101 exports bathymetry, side-scan, and snippetsdata in a standard format for easy interfacing.• Beamforming: The 7-P-1 Sonar Processor Unit performs initial signalprocessing, a combination of time delay and phase rotation beamforming.SeaBat 7101 Operator’s Manual Page 2 January 15, 2009Version 1F

INTRODUCTION• Bottom Detection: The special bottom detection algorithm uses acombination of center-of-energy and phase-zero crossing algorithms to detectthe bottom in each individual beam with the highest possible accuracy.• Auto Pilot: The Auto Pilot feature allows for automatic update of certain sonarsettings. When Autopilot mode is initiated, the SeaBat analyzes bottomdetection data to determine the average bottom depth and maximum usableswath angle, then optimizes the sonar settings accordingly.• Real-Time QC Display: The SeaBat 7101 generates a real-time display withan intensity image on a high resolution 17-inch LCD monitor. Overlaid on thisintensity image is the bottom detection display, giving the operator anexcellent QC tool.• Equidistant Footprint Selection: The SeaBat 7101 offers the operator achoice between 101 equiangular beams or 239 or 511 equidistant beams withthe 150° swath (and 141 equiangular beams with the optional 210° swath).All three options are dynamically focused.• Hardware Sync Pulse Out: A TTL pulse (synchronous with the transmitterpulse) is available from the 7-P-1 Sonar Processor Unit.• 1PPS Pulse Handling and Time Stamping: Data time stamping isreferenced to an incoming 1PPS and associated time message.• Adaptive Gating: Three different gate settings are available for applicationsto the bottom detect process: No Gates, Absolute Gates, and Adaptive Gates.• Beam Data Recording: The SeaBat 7101 is capable of producing a stream ofbeam data that is operator configurable and may be written to either the SPUlocal hard drive or an optional external RAID hard disk array. Data loggingsoftware controls recording, playback, and data storage functions.• Built-In Test Environment (BITE): BITE is an integral part of the 7-P-1 SonarProcessor Unit, monitoring the status of the link module and the wet-end units.1.5 Typical ApplicationsThe SeaBat 7101 is based around RESON’s third generation sonar processor unit, the7-P-1. This modular approach allows great flexibility and provides support for a widerange of applications including:• Harbor mapping• River surveys• Breakwater mapping• Revetment surveys• Pre- and post-dredging and condition surveys• As-built surveys• Pipeline route surveysSeaBat 7101 Operator’s Manual Page 3 January 15, 2009Version 1F

SAFETY PRECAUTIONS2 SAFETY PRECAUTIONS2.1 Operator SafetyThe SeaBat system should be handled with attention to operator safety as well asprotection of the hardware components. General precautions include:• DO NOT connect or disconnect cables with the power on.• DO NOT attempt to open and service the projector or receiver units.• DO NOT attempt to open and service the SPU.• DO NOT operate the system while divers are in the water and closer than twometers from the projector and receiver units. High-powered ultrasonic energycan be hazardous to human physiology.• DO NOT touch or handle any internal printed circuit boards without specificinstructions from RESON.2.2 Equipment SafetyEach SeaBat component is sufficiently robust for shipboard storage while in its owntransit case or shipping box, which include handles and tie-down rings. Use appropriatediscretion in lifting these components, as the cases may be awkward and heavy.2.2.1 Safe HandlingTo ensure safe handling of the equipment:• Inspect each transit case or shipping box for physical damage prior toopening, and each component for physical damage before installation.• Use adequate packaging and shock-absorbing materials to ship or store anyequipment outside the supplied transit cases.• Do not drop the equipment.• Do not connect or disconnect cables at the rear of the 7-P-1 SPU while theprocessor is running. This can damage the internal workings of the processor.• Do not place the sonar head in an area where the face may be scratched ordamaged. If an array must be placed on the ground, it should be placed on aflat surface and covered with a protective plastic sheet.• Do not place liquids on or near the equipment.• Do not smoke or spill ashes on or near the pointer device.• Ensure that the equipment is properly secured before putting out to sea.SeaBat 7101 Operator’s Manual Page 5 January 15, 2009Version 1F

SAFETY PRECAUTIONS• While operating in air, set your SeaBat system to the lowest possiblesetting. A higher setting may damage the transmit array ceramics. Thesystem should only be operated in air for very short periods of time.• Do not exceed operating and storage temperature limits.CAUTIONDo not operate transmitters in air with a power equivalent to180dB or more.2.2.2 Cleaning and MaintenanceThe acoustic window molded over the front of the projector and receiver arrays is madeof high-density polyurethane. A long range of chemicals will destroy the polyurethane,which include, but are not limited to:• Acids• Automotive brake fluid• Base• Grease• Halogenated hydrocarbons (carbon tetrachloride, trichloroethylene)• Hydraulic fluids• Ketones (MEK, acetone)• Nitro hydrocarbons (nitrobenzene, aniline)• Oil• Ozone• Petrol• Phosphate esterThe following recommendations are made to protect the arrays while in use and instorage.• For cleaning, use a mild, non-abrasive soap, fresh lukewarm water, and a softbrush.• Rinse the sonar with fresh water after every use.• Do not clean the array or sonar by using hot or cold pressure washers. Thehigh-velocity water spray will cut through the polyurethane or damage theinterface between the polyurethane and the sonar metal housing.• Do not apply any antifouling paint on the acoustic window unless the type isrecommended by RESON. The antifouling paint will affect the acousticperformance.SeaBat 7101 Operator’s Manual Page 6 January 15, 2009Version 1F

SAFETY PRECAUTIONS2.3 Electrical IsolationElectrical isolation for both titanium and aluminum components may be achieved byusing nonconductive bushings, washers, and isolation plates to insulate them from themounting brackets. Common nonconductive materials include Delrin, G-10 glass fibersheets, or high-density polyethylene sheets.NOTEContact RESON for additional information on schemes for electrical isolation.2.4 Exposure to SunlightDo not allow the transducer arrays to sit in direct sunlight when not in use. In addition tofurthering corrosive effects, continued exposure to ultraviolet (UV) rays will damage thepolyurethane array face.SeaBat 7101 Operator’s Manual Page 7 January 15, 2009Version 1F

BITE covers the following parameters:• Firmware version in use• Sonar head temperature• Internal voltages• Internal communications3.5 SeaBat 7101 Sonar HeadThe 7101 sonar head is the source of high power acoustic signals transmitted into thewater and received, amplified, and digitized in the receiver before being passed to theSPU.SeaBat 7101 Operator’s Manual Page 13 January 15, 2009Version 1F

COMPONENT DESCRIPTIONFigure 6: SeaBat 7101 Sonar HeadThe sonar head is a pressure-resistant cylindrical housing containing all requiredelectronics for system operation. Electronics in the sonar head include digital controllerand power supply, transmitter and receiver cards. The transmitter generates a pulse ofthe appropriate duration and amplitude and routes it to the projector.Signals returning from a target are amplified and digitized before being collected,formatted and transmitted to the SPU for signal processing and beamforming.The unit is constructed from aluminum or titanium depending on the depth rating.Titanium is suitable for long-term immersion in sea water. The sonar head is available indepth ratings between 100 and 3000 meters. For details on combinations of depth ratingand range, see section 3.3 above.Table 4: SeaBat 7101 Sonar Head Technical SpecificationsSpecificationMaterialDimensions 4excl. projectorValueAluminum, hard anodized andpainted or titanium alloy (optional)Width: 266mmDepth: 320mmWeightAluminum:Titanium:Air:26.8kgAir:40kgWater:4.8kgWater:18kgDepth rating100 and 120m (1500 and 3000mversions available)4 The indicated dimensions are for sonar heads for shallow water (100 and 120m ratings).SeaBat 7101 Operator’s Manual Page 14 January 15, 2009Version 1F

COMPONENT DESCRIPTION3.5.1 Sonar Head (Stick)The standard SeaBat 7101 sonar head is an integrated unit consisting of a receiver unitand a stick projector.3.5.2 Sonar Head (ER)The optional extended range SeaBat 7101 sonar head is an integrated unit consisting ofa receiver unit and an ER projector.3.6 CableThe SeaBat 7101 system consists of only one 25m cable that connects the sonar headwith the SPU allowing power and data to pass between the two units.SeaBat 7101 Operator’s Manual Page 15 January 15, 2009Version 1F

DATA PRODUCTS4 DATA PRODUCTSThe SeaBat 7101 produces three types of data:• Bathymetry• Snippets• Side-scanThe data is exported over gigabit Ethernet using TCP I/P protocol (UDP is alsoavailable).4.1 Bathymetry DataThe SeaBat 7101 generates 101 equiangular or 239 or 511 equidistant bathymetrysoundings per ping. The system broadcasts from the 7-P-1 SPU to the data acquisitionsoftware, where they are corrected for mechanical offsets, motion, heading, refraction,tide or depth, and position. (To perform these corrections, the appropriate sensors mustbe interfaced to the data acquisition software.)Depending on the beam angle, bottom type and signal characteristics, the bottomdetection method employed may be magnitude center-of-energy, phase slope zerocrossing,or a blend of the two methods. The bottom detection method can vary fromping to ping and beam to beam.4.2 Snippets DataSnippets data is available from the SeaBat 7101, which consists of a windowed selectionof samples containing both amplitude and phase information (if selected).A snippets data sample contains corrected backscatter data from the ‘footprint’ on theseabed illuminated by a single sonar ping. The number of snippets in a swath is afunction of the number of sonar beams. The length of each snippet depends on theoperating mode, beam number, and depth. All of these settings may be selected by theoperator.Each snippets data packet contains pertinent information such as time stamp, sequentialping number, sample rate, sound velocity, and operator settings such as power, gain,absorption, and range scale.4.3 Side-Scan DataSide-scan swath is measured and displayed without degrading any of the traditionalsurvey capabilities of the SeaBat.SeaBat 7101 Operator’s Manual Page 16 January 15, 2009Version 1F

DATA PRODUCTS4.3.1 Side-Scan Imagery DataSide-scan forms an image of the seafloor which can be used to locate and identifyfeatures and bottom conditions. Each sonar ping is used to generate a line of data. Eachline contains a series of amplitudes representing the signal return versus time or range.When a series of these lines is combined and displayed as the vessel moves along thetrack, a two-dimensional image is formed, providing a detailed picture of the bottomalong either side of the vessel.Side-scan data is displayed as an array of amplitude values which represents theamplitudes for each sample cell in the beam from a single ping.NOTESide-scan cannot be used to accurately measure true depths, but it can provide amore detailed picture of the seafloor. This image can be used together with bathymetryto identify features and to help ensure that the survey does not miss any small butsignificant targets.4.3.2 Side-Scan BeamformingThe beamforming process combines one half of the bathymetry beams into two sidescanbeams. The process combines adjacent pairs of beams by averaging, thencombining the averages by selecting the brightest points from the averaged beams. Thecombination process uses peak-detect determination and yields a less “noisy” output.The bathymetry and side-scan data are independent in the beamforming process and inhow the output data is generated.4.3.3 Side-Scan Data OutputThe array of intensity values is a series of amplitudes, one for each sample interface foreach side-scan beam. A sampling rate of 15,000 samples per second providesapproximately one measurement for every 5 centimeters of range.The number of intensity values reported in a side-scan packet is a function of range. Thenumber of values per packet can be calculated using the following formula:Side-scan is one of the many records available for subscription from the 7k Centersoftware. Refer to the 7k Data Format Definition for further information regarding sidescandata output (see also Appendix A Reference Documentation).SeaBat 7101 Operator’s Manual Page 17 January 15, 2009Version 1F

INSTALLATION INSTRUCTIONS5 INSTALLATION INSTRUCTIONS5.1 Installation ChecklistNOTEThis checklist only covers the most basic, standard system installation. Depending onthe system configuration or specific customer requirements, this list may or may notapply.Follow these basic steps to install and configure your new SeaBat sonar system:• Install the dry-end components:o 7-P-1 SPUo Monitor, keyboard, mouse• Install the wet-end components:o Sonar head• Install and connect cables:o Processor to sonar head cableo Auxiliary sensor cableso Monitor, keyboard, and mouse connectionso SPU power cable• Power up the system• Test the system• Configure the SeaBat software5.2 Dry-End Installation5.2.1 SPU InstallationThe SPU may be either rack mounted or table mounted. It must be in an area that is notexposed to the weather, but is within easy reach of the operator workstationconnections. Allow clearance around the unit to provide adequate air circulation andeasy access to the power switch.After the SPU is installed, the only interaction required should be to press the powerswitch and energize the system.SeaBat 7101 Operator’s Manual Page 18 January 15, 2009Version 1F

INSTALLATION INSTRUCTIONSNOTEAlthough RESON does not provide slides or rails for rack-mount arrangements,mounting holes have been provided on the chassis for this purpose. For rackinstallation, follow the instructions provided by the manufacturer.5.2.2 SPU Cable ConnectionsThis section to be updated!Most of the cable connections on the dry end are made directly into the rear panel of theSPU.CAUTIONDo not disconnect any cables from the rear of the 7-P-1 SPU while the unit is running.This can damage the internal workings of the processor.There are several cable connections to be made at the dry end of the installation. Theseconnections are between the SPU and its peripheral equipment, between the SPU andthe operator workstations, and between the SPU and the sonar head.The cable connections from the sonar head to the SPU should be made prior toimmersing the unit in water. Place a light coating of grease on the connector face toensure sealing.Verify that all cables are securely fastened and that strain relief is provided to preventcable damage. Standard cable length between the sonar head assembly and the SPU is25 meters.The critical connections are shown in the following illustration. All dry-end cables comewith factory-installed connectors and just need to be attached at the appropriate port(s).SeaBat 7101 Operator’s Manual Page 19 January 15, 2009Version 1F

This ensures thatnoise from surface waves and turbulence generated by the mounting structure does notdegrade performance. Mounting may be over the side, over the bow, or though a moonpool. Ensure that submersion depth is sufficient to avoid shadows from the keel, hull orother obstacles.SeaBat 7101 Operator’s Manual Page 20 January 15, 2009Version 1F

INSTALLATION INSTRUCTIONSNOTEThe sonar head is not designed to be hydrodynamic at speeds in excess of two knots.Vibration and oscillation will become evident, if the projector and receiver are notrigidly mounted. To minimize the unsupported length, place a support as close to thewaterline as possible. Fairings can also be used to improve hydrodynamicperformance.5.3.2 Sonar Head Assembly OrientationThe sonar head assembly should be mounted with the receiver array oriented verticallydownwards and the projector facing aft. If necessary, the projector may be orientatedforward or the sonar head rotated away from vertical with allowances made in theprocessor setup and data acquisition software.Figure 8: Sonar Head Assembly OrientationCare should be taken to ensure that the head is parallel, as closely as possible, to thehorizontal plane of the vessel or ROV. Small errors in mounting can be compensated forby postprocessing data acquisition software.5.4 System CheckoutOnce the SeaBat 7101 has been installed, follow these steps to ensure that the systemis working properly.1.

SYSTEM OPERATION7.3.5.2 Recommended ActionsIn most cases, information is provided to the operator to rectify the problem. For instancean alarm indicating missing sound velocity input to the processor will require theoperator to check the instrument and the input.If errors occur that result in a condition where the systems in not operable the followingactions are recommended.1. Exit any active applications.2. Shut down the 7-P-1 SPU completely.3. Restart the 7-P-1. Use SHUTDOWN from the menu rather than RESTART.4. If the condition persists after a shutdown and restart, contact RESONService (support@reson.com).For a description of event messages and recommended actions, see section8 Troubleshooting.7.3.6 Freeze the Sonar ImageClicking the Freeze button prevents the image on the Primary Display tab from beingupdated while all other sonar functions continue. This allows prolonged viewing of aparticular item.Click the Resume button to allow updates to continue.7.3.7 Maximize the Sonar ImageClicking the Max button hides the lower set of tabs and enlarges the sonar image to fitthe entire SeaBat window. This allows close inspection of data.Click the Min button to return the image to normal size and display the lower set of tabs.7.3.8 Change ModesThe Mode drop-down menu allows the operator to select to view the current data beingcollected or to view a playback of a previously collected file.SeaBat 7101 Operator’s Manual Page 52 January 15, 2009Version 1F

SYSTEM OPERATIONTo select the desired mode, click the drop-down menu and select one of the followingoptions:7.3.9 Auto Pilot• Manual: View data being collected now.• Auto Pilot: Disables the operator selection of certain parameters (such asrange, gain, power) and allows the SeaBat to automatically adjust sonarsettings based on the bottom detection data. For details, see section 7.3.9below.• Playback: View a previously collected data file. Selecting Playback modeadds the Playback tab to the lower set of tabs.The sonar can be switched to Auto Pilot mode by selecting this option from the Modedrop-down menu. This disables operator selection of certain parameters such as range,gain, and power until the Manual mode is reselected.Once Auto Pilot mode is initiated, the 7k Center analyzes bottom detection data fromsome number (N) of pings. If at least M of those pings are judged to have good bottomdetection quality, the average bottom depth and maximum usable swath angle aredetermined.Once depth and maximum swath angle are determined, an appropriate range setting isdetermined and commanded to the sonar. The process then repeats for the next Npings, etc. If too few of the N pings are judged to be good (for example, if the waterdepth exceeds the current range), the Auto Pilot will command the next greater rangesetting to the sonar before analyzing the next N pings. This way Auto Pilot mode can bereset to the minimum range and it will incrementally try greater ranges until the bottom isfound.In addition to controlling the range, Auto Pilot mode also automatically adjusts sonarparameters (power, gain, pulse length, and maximum ping rate). A user editable table ismade up of rows, each corresponding to a minimum and maximum range and includinga set of parameters. Depending on what row the current range setting falls within, theparameters for that row will be commanded to the sonar. This way, critical sonar settingsas well as range are all automatically controlled when in Auto Pilot mode.7.3.9.1 Auto Pilot SettingsThe data contained within the look-up table is specific to a sonar type and may bemanually edited. These settings are specified by the operator prior to initiating Auto Pilotmode. To modify the default parameters, select Edit Auto Pilot Settings from theConfiguration menu and make changes by clicking the arrow buttons next to the desiredsetting.SeaBat 7101 Operator’s Manual Page 53 January 15, 2009Version 1F

SYSTEM OPERATIONA default set of values are included in the table which may require modification based onthe specific conditions encountered.7.3.9.2 Auto Pilot LimitationsThe Auto Pilot functionality is difficult to optimize for all imaginable conditions and itshould be expected that occasionally, the functionality will fail when subjected tomarginal conditions. Occurrences such as rapidly changing seafloor topography, poorsignal-to-noise ratio (possibly when operating at extreme ranges) and environmentalconditions such as flow noise, bubbles around the array, and bio activity could all causeintermittent failure of Auto Pilot.7.3.10 Identify Beam Track, Depth, and Range (or Channel and Sample)To the right of the Mode drop-down menu the beam Across Track, Depth, and Rangereadings are displayed for a particular point on the sonar wedge display. Readings are inmeters.These numbers change as the pointer passes over the sonar image, indicating thepointer’s current position on the image.When Beam has been selected from the Display Format drop-down menu, the readingswill indicate channel and sample as the pointer passes over the B-scan display (see alsosection 7.3.3 above).SeaBat 7101 Operator’s Manual Page 54 January 15, 2009Version 1F

SYSTEM OPERATION7.4 Changing the Sonar Settings7.4.1 Main Sonar SettingsThe Main Sonar Settings tab is the control point for the projector and receiver units.Figure 14: Sample of Main Sonar Settings TabNOTEFor all sliders on the Main Sonar Settings tab, except the Power control, the newsettings will not be sent until the mouse has released control of the sliders.7.4.1.1 Set the RangeThe Range setting determines how far the SeaBat will “see.” The range settings areoperator selected. There are multiple settings in discrete increments. For the SeaBat7101 these settings range from 1 to 500 meters.Select the appropriate range scale to keep the horizontal bottom image at or above thewidest part of the sonar wedge:Figure 15: Range Setting DiagramsDiagram A depicts a proper range setting. Diagram B depicts an acceptable rangesetting for a swath that is beginning to fade due to the effects of attenuation andspreading loss. Diagram C depicts an incorrect range setting. Notice that the stilluseableends of the swath are being cut off by the limits of the range setting.7.4.1.2 Set the Transmit Power (Power)The Power setting allows the operator to increase or decrease the amount of power(acoustic energy) transmitted into the water. There are multiple increments (OFF to210dB for ST and OFF to 220dB for ER), each accounting for an increase ofapproximately 3dB.SeaBat 7101 Operator’s Manual Page 55 January 15, 2009Version 1F

SYSTEM OPERATION7.4.1.3 Set the Maximum Ping Rate (Max Rate)In some instances it may be beneficial to force a lower ping rate than the normal rateassociated with a particular range. Examples of this would be instances when the vesselis moving at a very slow rate, and the operator wants to eliminate redundant data; orwhen the vessel is in a high-reverb environment where echoes of the previous ping arecontaminating the current ping.The Max Rate setting allows the operator to limit the number of pings per second (p/s),making it lower than the standard ping rate for that range setting. For the SeaBat 7101the ping range available is from OFF to MAX, which means that the operator mustchange the range to change the ping rate.NOTEIf Max Rate is set to 0, the system will not ping or receive data. If Max Rate is sethigher than the sonar’s actual maximum ping rate, the sonar will ping at its actualmaximum ping rate.7.4.1.4 Set the GainWhen operating in TVG mode, the Gain setting allows the operator to select the amountof receiver gain applied to the returned sonar signal (in addition to the calculated gain).The gain range available is from 0 to 45dB.When operating in Fixed mode, the gain cannot be changed.The last setting for each mode is remembered and restored when mode is changed.NOTEThe SeaBat system utilizes Time-Varied Gain (TVG) by applying a variable gain to thesignal, based upon the following formula:Where:α = Absorption loss in dB/kmSp = Spreading loss coefficientR km = Range in kilometersR m = Range in metersG = Extra gain from RxGain menu itemReceiver Gain = 2 α R km + Sp log R m + GSeaBat 7101 Operator’s Manual Page 56 January 15, 2009Version 1F

SYSTEM OPERATION7.4.1.5 Set the Pulse LengthThe Pulse Length setting allows the operator to change the pulse length of thetransmitted signal. For the SeaBat 7101 the pulse lengths available are from 21µs to225µs in discrete increments.NOTEFor a given power setting, a narrower pulse length provides a higher resolution at ashorter range. A wider pulse length provides maximum range with lower resolutionimage results.7.4.2 Applying GatesThe Gates Settings tab allows the operator to apply range and/or depth filters (depthgates) to the bottom detection process to aid in noise reduction and to correct for a tiltedsonar head. Gate lines (filter lines) can be optionally displayed on the sonar image. Fordetails, see section 7.4.4 below.A yellow highlight of text fields and check boxes indicates that the data was changedsince last update and has not yet been applied.The color of the Update button indicates if data is stored locally by the UI or sent directlyto the center:• Red – Data is stored locally and gates are inactive• Green – Data is sent to center and gates are activeFigure 16: Sample of Gates Settings Tab7.4.2.1 Gate Control SwitchThere are three gate modes:• Absolute• Adaptive• No Gates (gate functionality is turned off)If you switch gate mode, the data stored last time the Update button was clicked for thatmode will automatically be sent to the center.SeaBat 7101 Operator’s Manual Page 57 January 15, 2009Version 1F

SYSTEM OPERATION7.4.2.2 Absolute Gate ParametersWhen Absolute gating is selected, either gate range or depth is entered in this section.Select the Enable check box for the type of gate desired.• Range: Applies the minimum and maximum range values as entered in theMinRange and MaxRange fields. Only bottom returns within these range limitswill be used in the bottom detection process.• Depth: Applies the minimum and maximum depth values as entered in theMinDepth and MaxDepth fields. Only bottom returns within these depth limitswill be used in the bottom detection process. Use of a motion sensor isrequired to maintain constant depths during the ship’s normal pitch and rollaction.Click the Update button to finalize changes.7.4.2.3 Adaptive Gate ParametersWhen Adaptive gating is selected, the bottom is tracked based on window size andsearch criteria from beam to beam within a ping.• Enable Nadir Search Gate: Applies the minimum and maximum nadir depthvalues as entered in the MinDepth and MaxDepth fields to refine the initialsearch for the strongest bottom return from the nadir beam. This initial searchgate can be enabled or disabled. See also section 7.4.2.4 below.• Adaptive Window Size: Applies the percentage value as entered in theAdaptive Window Size based on the total samples in the ping. Once the initialbottom detection point is located, the gates are propagated in each directionusing this number. The bottom detection from beam to beam is thereforebased on the results from the previous beams. Increasing this window sizeallows more samples to be included in the detection process, but may alsointroduce noise. Decreasing this window size too much may degradeperformance, when the bottom is not flat.Click the Update button to finalize changes.7.4.2.4 Automated Nadir Search GateWhen Adaptive gating is selected and the Enable Nadir Search Gate box checked, awindow appears on the Primary Display, delimited by yellow horizontal lines labeled NS.As the filter limits approach the nadir search limits, the NS gates are automaticallyupdated to center the nadir search on the detected seafloor.The NS gates can be moved manually with the mouse/trackball and selecting MoveNadir Gate.SeaBat 7101 Operator’s Manual Page 58 January 15, 2009Version 1F

The range available is from 0 to 120dB/km.This value is used in conjunction with the spreading loss coefficient to compute the TVGcurve as described in section 7.4.3.2 below.7.4.3.2 Change the Spreading Loss Coefficient (Spreading)The Spreading slider allows the operator to enter the amount of cylindrical and sphericalspreading loss that is expected through the ambient water medium. The range availableis from 0 to 60dB, with a recommended initial value of 30.This coefficient value is used in conjunction with the absorption loss value (see 7.4.3.1above) to compute the TVG curve applied to the returned signal.SeaBat 7101 Operator’s Manual Page 59 January 15, 2009Version 1F

SYSTEM OPERATION7.4.3.3 Set the Sound Velocity (Sound Velocity)The Sound Velocity slider allows the operator to enter the externally measured speed ofsound through the local water. This value is represented in meters per second, and isused in Range display and Receiver Beam Steering.The range allowed is from 1400 to 1600m/s. If the local sound velocity is not known,RESON recommends a value of 1480 to 1500m/s for open sea areas and 1425m/s forfresh water. The following figure provides general reference for typical surface soundvelocity at different temperatures and salinity.Figure 18: Sound Velocity ReferenceNOTEIf a sound velocity probe is interfaced to the sonar processor, the Velocity value iscontrolled by the probe and cannot be changed by the operator.7.4.4 Primary Display SettingsThe Primary Display Settings tab allows the operator to customize some of the visualproperties of the sonar image.Figure 19: Sample of Primary Display Settings TabSeaBat 7101 Operator’s Manual Page 60 January 15, 2009Version 1F

Configuration isdone through this interface, which sets up the I/O module installed on the 7-P-1 SPU.The data acquired by the I/O module is routed to the SeaBat in real time to allow foraccurate time stamping and beamforming.Figure 20: Sample of I/O Module Setup Tab• Device List: This frame displays the current list of devices.• New: Create a new I/O device.• Edit: Edit an existing I/O device.• Remove: Delete an I/O device from the list.• QC: Launch the 7k external I/O monitor window.• Device Status Display: Shows the status of the corresponding device in theDevice List frame.• Clear Status Display: Clears and resets the status display.SeaBat 7101 Operator’s Manual Page 62 January 15, 2009Version 1F

SYSTEM OPERATIONNOTEAccuracy of the bathymetric data depends entirely on valid time sync and SVP inputfrom this module, unless another solution such as PDS2000 is being used to performthis function.In the absence of time sync, a software time stamp is employed. However, this usuallyresults in poor data quality, as the time stamp is applied AFTER the last sample isreceived.In the absence of SVP input, the input from the Ocean Menu tab is used instead.7.5 Data Recording and Playback7.5.1 Recording Sonar DataThe Data Recording tab is divided into three general sections:• Recording Control• Advanced• Recording StatusFigure 21: Sample of Data Recording Tab7.5.1.1 Recording ControlThe Recording Control section of the Data Recording tab allows you to start and stop thedata recording process.

SYSTEM OPERATION7.10 Equidistant BeamformingAs the beam steering angle increases from nadir, the number of beams per degree ofswath stays constant for equiangular spacing while it increases for equidistant spacing.Figure 25 presents the number of beams as a function of steering angle for a 1° nadirbeam spacing.Figure 25: Beam DensityAssuming a flat bottom and using the beam footprint generated by the nadir beam, itmay be seen that the center-to-center spacing for each beam successively reduces asthe departure from nadir increases until at ±65° the beam density is approximately 2.5times greater than at nadir.Assuming one sounding is generated from the intersection of the beam center with theseafloor, in equidistant mode, the appropriate number of beams is formed to maintainthis nadir sounding spacing across the entire swath. See also Figure 26.SeaBat 7101 Operator’s Manual Page 80 January 15, 2009Version 1F

SYSTEM OPERATIONReduced Center-to-Center Spacingat Large Steering AnglesWider Center-to-CenterSpacing at NadirFigure 26: Beam SpacingIn order to achieve this uniform sounding spacing, it is necessary to decrease the beamcenter-to-center spacing requiring a significant increase in the number of beams formed.As an example, in the SeaBat 7101 240kHz system 101 beams are formed inequiangular mode and 239 or 511 beams in equidistant mode over the same 150°swath.The beamformer is able to generate a receive beam centered on any angle within theavailable swath and in equidistant mode a set of coefficients is selected that form a setof receive beams that are centered on the midpoints of the footprints.Figure 27 shows the difference in distribution between equiangular and equidistantmodes.Figure 27: Across-Track Sounding Location on a Flat BottomSeaBat 7101 Operator’s Manual Page 81 January 15, 2009Version 1F

SYSTEM OPERATION7.11 Quality FlagsAs part of the 7k 7006 record, a one-byte quality flag is exported indicating the quality ofthe bottom detection point. Two bits are used with the following parameters:• Bit 0: Brightness: 1 = pass, 0 = fail• Bit 1: Colinearity: 1 = pass, 0 = fail• Bit 2: Reserved quality bit• Bits 3-5: Process bits• Bits 6-7: ReservedThere are therefore four quality levels:• 0: Brightness and colinearity fail• 1: Brightness pass, colinearity fail• 2: Brightness fail, colinearity pass• 3: Brightness and colinearity pass7.11.1 Display in the SeaBat 7k UIThe wedge display in the SeaBat UI can display the bathy points color-coded to indicatewhich quality flags have passed:7.11.2 Brightness Test• Green: Both brightness and colinearity tests passed• Orange: Brightness test only passed• Yellow: Colinearity test only passed• Red: Neither test passedThe brightness test measures the signal-to-noise ratio (SNR) of the signal strength(magnitude) near the bottom detection point (as determined by the bottom detectionalgorithm) versus the background noise in the rest of the beam.The signal strength is the mean of the square of the sample intensity around the bottomdetection point. The number of samples used is marked ‘A’ in Figure 28 and is a smallpercentage of the total number of samples. The noise is based on a mean of the squareof the samples in the second half of the “tail” of the detection window (marked ‘B’ inFigure 28) and the square of the samples in the “head” of the water column (before thefirst return – marked ‘C’ in Figure 28).Beams, whose SNR is greater than a predetermined threshold, will be flagged aspassing the brightness test.SeaBat 7101 Operator’s Manual Page 82 January 15, 2009Version 1F

SYSTEM OPERATIONFigure 28: Brightness Test7.11.3 Colinearity TestIn general terms, this test will pass if a bottom detection point sample number for a givenbeam falls on or near a line drawn through its neighboring beams' bottom detectionpoints. This is achieved using a moving polynomial fit of the points on either side of eachpoint. If point N is within a window of the line fit it is marked colinear.This process is done in stages that begin with the central beams and moving outward oneach side of the wedge in turn.Line fitWindow extentPoint flagged with Poor colinearityFigure 29: Colinearity Flags7.12 7k Center Console WindowThe 7k Center runs in console mode only. The non-resizable black console window isactive while controlling the sonar. On startup and shutdown progress information isposted to this window. All other sonar information that was previously reported in theconsole window is now obtained from the display.SeaBat 7101 Operator’s Manual Page 83 January 15, 2009Version 1F

SYSTEM OPERATION7.13 Remote OperationThe 7k series software architecture is built on a client/server concept. The 7k Centerrunning on the 7-P-1 SPU controls the sonar, performs data processing, and exportsdata to external clients connected via TCP IP or UDP Ethernet connections. It is normalto run client applications such as the GUI (Graphical User Interface) on the 7-P-1platform, but clients may also be run remotely.If the 7k GUI (SeaBat7K.exe) is started on a remote machine which does not have a 7kCenter running, the user is prompted to enter an IP address for the machine running thecenter. This way the GUI can be run remotely.Depending on Ethernet bandwidth and traffic load, remote operation may result inreduced performance or, in some severe cases, data loss.The following files, all from the RESON directory on the 7-P-1 SPU, must be copied to adirectory on the remote PC (RESON recommends placing these files in the "ProgramFiles" directory).• SeaBat7k.exe• MathUtils.dll• TrueTimeSDK.dll• XGRAPH10.dll• RSBDirTree.dllNOTEA shortcut to SeaBat7k.exe can be placed on the desktop foreasy program start.7.14 Sharing a Folder on a NetworkThis section describes how to create a shared folder on the 7-P-1 SPU. Shared foldersallow users to access and move data off the 7-P-1 to another network-connected PC.NOTEA network switch is recommended for ease of file sharing and high-speed data transferreliability.1.
