✦ Synopsis

Various theories (I-7) on scattering of electromagnetic waves from rough surfaces have been developed in recent years dealing mostly with the polarized scattered signal. A recent theory (8) bva8 developed for both the polarized and depolarized return signals along the ~~rc~o~-~u~gens approach. This approach, hawever, is restricted by the tangent plane approximation to a single watterhg process which predicts no depolarisation for a perfectly conducting surface, It also predicts a smaller depolarized return near vertical than at larger incident angles [axept; ntxar g,rt&ng:). This predicticrn appears to be in agreement with some sea experiments (3) but is not in agreement with certain moon experiments (10, I I) and some laboratory experiments (Xi!}. Consequently, a different approach seems necessary. In this paper, we consider a slightly rough Fourier ~~~~~~~M~~~$ surfxe and a horkontsBy peIariaed incidenk plane waGe_ Ekattered fields are given in a perturbation se&s and are required to satisfy the exact boundary conditions.
