Bottom Backscattering Measured Off the Southwest Coast of Florida During the Littoral Warfare Advanced Development 99-1 Experiment

Measurements of ocean bottom backscattering were performed in a shallow water environment off the southwest coast of Florida as part of the Littoral Warfare Advanced Development 99-1 Experiment. Scattering strengths were obtained at 1 to 4.5 kHz as a function of grazing angle. Scattering strengths were in the -35 to -45 dB range. The grazing angle dependence could be fit adequately by assuming a dependence of scattering strength on the sine of the grazing angle.
