Backscattering of Radar Waves from a Tilted, Slightly Rough Surface

Abstract

This report presents the derivation of an equation for the radar backscatter coefficient from a titled, slightly rough surface. The basic technique employed in the solution is the small perturbation method, along with the Fourier transform. The incident wave is allowed to have an arbitrary polarization, and specific results are shown for horizontal, vertical, circular, and elliptical polarizations. One conclusion of this report is that the influence of a given slope of the tilted rough surface, upon the calculation of the radar backscatter coefficient, depends upon the polarization of the incident electromagnetic wave.
