Bottom Backscattering Measured Southwest of Key West During Littoral Warfare Advanced Development Focused Technology Experiment 97-2
1997
Soukup, Raymond J. | Edsall, Douglas W.
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 Lambert's 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.
