Evanescent Acoustic Wave Scattering By Targets and Diffraction by Ripples

Abstract

The main objective was to understand consequences of incident wave evanescence on (existing or under-utilized) scattering observables. It was 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.
