Reson Seabat 8101

Options and Upgrades4.5.2 Snippets Imagery DataA Snippet is the series of amplitude values in the signal reflected from a beam‘sfootprint on the seafloor. One Snippet will be produced for each beam for eachsonar ping (see Figure 17). The length of each Snippet will vary as a function ofthe individual beam angle, seafloor depth, and the Snippets operating mode. Ifthe Snippets data for each swath is concatenated, with each individual beamcentered at its corresponding bottom detect point (footprint) location, the combinedseries will provide a result similar to slant range corrected sidescan imagery(see Figure 18). In most cases, this will provide 100% coverage of theseafloor.See paragraph 6.3.10 for additional information on Snippets data format.Figure 17.
