Abstract:

The objective is to understand the theory of acoustic scattering from rough surfaces, with applications to ocean surfaces. It is necessary to develop multiple scattering models that are able to treat larger values of roughness, as well as to incorporate as much information as possible into a statistical description of the surface. The mathematical methods we have developed are generic in the sense that they can also be applied to any rough surface. Enhanced backscattering can result when the surfaces are very rough. We have found additional new results for the coherent specular intensity and the backscatter enhancement effect for the direct scattering problem. In addition, we have reconstructed surface profiles from scattered field data using two different approaches.
