Evanescent Acoustic Wave Scattering by Targets and Diffraction by Ripples

Abstract

The goal is to develop and test certain ideas relevant to the coupling of sound with small targets buried in the ocean bottom. This is a "Graduate Traineeship Award" in Ocean Acoustics. The main objective is to understand consequences of incident wave evanescence on (existing or underutilized) scattering observables. It is also planned to explore conditions whereby surface roughness enhances the coupling of sound to simulated buried targets. Resolving these issues should be helpful for discriminating between echoes from real buried targets and background objects.
