Specular Scattering of Acoustic Waves from a Rough Surface in the Fraunhofer and Fresnel Approximations

Abstract

This document presents the results obtained in an experimental and theoretical study of the scattering of underwater acoustic waves from a rough surface. Measurements were used to calculate the amplitude fluctuations, the phase fluctuations, and the scattering coefficient. Theoretical formulas were developed for the fluctuations and the scattering coefficient in the Fraunhofer and the Fresnel approximations for the specular direction.
