Abstract

In Section 1 the Rayleigh reflection coefficient for a rough surface is derived in a form suitable for inclusion in the basic integral for the scattered pressure. A formula for the pressure scattered from a rough attenuating surface is then derived using this coefficient. The backscattered intensity is calculated in Section 2 for various assumed distributions of surface heights. The results presented here are restricted to the high frequency limit, and are developed using both the stationary phase and the modified Fresnel techniques. Finally, a backscattering result for a composite surface is derived, and is shown to be consistent for both forward and backward scattering. (Author)
