Backscattering Enhancements from Caustics Produced by Rippled Surfaces

Abstract

The goal is to develop and test the hypothesis that certain paths associated with rays reflected from rippled surfaces enhance the backscattering of sound by small targets. The enhancement of the scattering by the small target should be important for targets situated close to a reflection caustic of the rippled surface. This is a "Graduate Traineeship Award in Ocean Acoustics."
