Bistatic Scattering Cross Sections of a Composite Rough Surface

Abstract

The notion of shadowing is important in the analysis of scattering from rough surfaces using the Kirchhoff method. A key role is played here by the visibility function, which acts as a correction to the usual' scattering cross section. The surface under consideration is a normally distributed composite rough surface. Analytical results are provided for the bistatic scattering cross sections. Included herein is a derivation of the visibility function. Some properties of the visibility function are highlighted in a discussion. An important feature of this work is that our expressions for scattering cross sections, in contrast to those of Sancer (1969), are free from discontinuities and hence physically more appropriate.
