摘要：

A full-wave approach based on the complete expansion of the EM fields and the imposition of exact boundary conditions is presently used to convert Maxwell's equations into rigorous sets of generalized telegraphists' equations for the forward- and back-scattered wave amplitudes of rough surfaces having different roughness scales. The single-scatterer approximations of the rigorous full-wave solutions indicate that the enhanced like-polarized and cross-polarized backscatter is a first-order effect; for normal incidence, the full-wave solutions for the bistatic like- and cross-polarized cross sections exhibit the observed threefold symmetry about the backscatter direction.
