Rough Surface Backscatter
Abstract
The intent of this contract was to further analyze some model computations of backscattering strength which were done in summer of 1987. This computational model tracked (with a 3-5 dB difference), the Chapman-Harris-Scott empirical model for backscattering over a wide range of parameters, (150-1200 Hz, 10-45 deg. grazing, and 10-40 knots winds). However, the computation was not properly windowed, and when a suitable window was introduced the computational backscattering strength agreed very closely with the standard perturbational model for backscattering. It also seems very likely that this approach can be modified to address scattering from rigid boundary, i.e., the rough ocean basement. As more accurate spectral models of the ocean basement are becoming available, computer simulated basement surfaces can more accurately model the actual surface. Acoustics.
