An Approximate Technique for Extracting the Surface Reflected Plane Wave Spectrum from Certain Acoustic Propagation Models

Abstract

Over the past decade, advances in the areas of propagation and rough surface scattering have made attractive the concept of generating hybrid models to investigate the impact of realistic two dimensional sea surface roughness on long range acoustic propagation. The development of such models requires that efficient and accurate coupling schemes be created. In this paper, one aspect of this coupling problem is discussed; generating a suitable representation of the incident field for input into the scattering model....
