Numerical Studies of Rough Surface Scattering Models
Abstract
A practical rough surface scattering model based on the non-local small slope approximation (NLSSA) [1],[2] is being developed and examined for pressure-release surfaces and fluid-fluid interfaces. To be practical, a rough surface scattering model must be easy to implement and easily incorporated into existing propagation models. At the same time, it must be accurate enough to give useful results. For purposes of this research, practical means that a rough surface scattering model must satisfy the following requirements: 1. No more than N-D integration away from low grazing angles, where N represents the dimension of the surface 2. No more than 2N-D integration at low grazing angles 3. Accuracy to within a few dB.
