Numerical Studies of Rough Surface Scattering Models

Abstract

My long-term goal is to be able to predict the effects of a rough air-sea interface and a rough seabottom interface on acoustic propagation. These are of particular importance for multiple surface interactions which can occur in shallow water environments. I have continued to work on the development of theoretical surface scattering models. My objective is to discover or devise a model that accurately predicts scattering from rough surfaces but which also can be used in practical models of acoustic propagation and scattering. In conjunction with this objective, I have been working with another ONR researcher to develop an exact numerical method for testing the accuracy of theoretical models.
