Measurements of ocean bottom backscattering were performed in a shallow water environment southwest of Key West, Florida. as part of the Littoral Warfare Advanced Development LWAD Focused Technology Experiment 97-2 FTE 97-2. Scattering strengths were obtained at 2, 2.5, 3 and 3.5 kHz as a function of grazing angle at a single site with a sandy bottom. The scattering strengths roughly followed a Lamberts Law dependence on the square of the sine of the grazing angle dependence with constants ranging from -22 dB for 2000 Hz to -19 dB for 3500 Hz. This frequency dependence was consistent with the results given by the Mourad-Jackson bottom scattering model.
