Scattering and Depolarization by Random Rough Terrain and Vegetation Covered Terrain-Unified Full Wave Approach,

Abstract

In this paper the principal elements of the full wave approach to problems of scattering the depolarization by rough terrain and vegetation covered terrain are presented. Scattering by random rough surfaces is considered in detail and the full wave solutions are compared with earlier solutions based on geometric optics, physical optics and perturbation theories. It is shown that since the full wave approach accounts for both specular point scattering as well as Bragg scattering in a self-consistent manner, it resolves the discrepancies between the physical optics and perturbation solutions and bridges the wide gap between them. Thus, on applying the full wave approach to scattering by composite random rough surfaces it is not necessary to adapt a two-scale model of the rough surface.
