RF Open-Loop System TestingRF/MMWReceiverUnder TestAFEWES offers a versatile, realisticdense RF environment. Testing ofRF/Millimeter Wave (MMW)receivers, Radar Warning Receivers,and the receiver processors of ECMsystems, is accomplished using theMultiple Emitter Generator (MEG).The MEG can generate realisticallydense, theaterspecificemitter laydowns with a onehalfsecond scenario update rate. Avast array of scenarioinstrumentation options is available.Seventy-three (73) dedicatedinstantaneous sources/emitters areprovided with up to 20 complexwaveform (PD) sources. Multiplexingexpands this capability to 217emitters of hostile, neutral, andfriendly signals.RF coverage is available from 0.5 to18.0 GHz, 30 to 40 GHz, and 90 to100 GHz amplitude AOA only. Ifrequired, the National Imagery andMapping Agency-based terrainmasking effects can also beincluded..Airborne Emitters
RF Closed-Loop System TestingAFEWES RF Closed-Loop threatsimulations are based on aniterative, real-time solution of theradar range equation, based on theaircraft and missile flight paths.Databases representing the radarcross section (RCS) of the victimaircraft, the transmit and receiveantenna patterncharacteristics of the System UnderTest (SUT), and threat antennacharacteristics provide inputs tosimulation.Actual EW systems can be placed in asecure shield room and interfaced to. the AFEWES threat simulationsthrough RF wave guides.Alternately, the JammEr TechniquesSimulator (JETS) is used togenerate certain classes of EWwaveforms if actual equipment isunavailable.Simulation Attributes Provide Engagement Fidelitywith High Throughput (100+ runs/day)Rear Reference Direct RaySeeker ClutterRear Reference Clutter‣ TTR‣ Clutter‣ Target Signature‣ EC System‣ Seeker‣ Missile / target• OAR or Digital• Terrain, site-specific, generic,JEM• All Aspect RCS(scintillation/glint)• SUT or simulated• Angle/Doppler track loop• High fidelity antenna patterns• Guidance computer• Real-time flight kinematics
