Numerical Studies of Rough Surface Scattering Models

Abstract

This final technical report summarizes the results of work performed between 1 Sep 89 and 31 Mar 97 or accomplishments achieved as a result of this work. Finite-Difference Time-Domain code was developed for rough surface scattering. The phase perturbation, small slope approximation, local parabolic approximation, and nonlocal small slope approximation models for rough surface scattering were developed and examined for a number of different spectra and surface types.
