Diffuse scattering from rough surfaces

The problem of diffuse scattering from ocean surfaces defined by a normal stochastic process is under taken. It is assumed that the surface height profile is the sample mean of the number of profiles obtained for the random rough surface. Theoretical expressions for the returned power are developed by using the Helmholtz integral approach with Kirchhoff's approximations for the plane wave case. The plots of scattered power verus surface height roughness parameter are presented.
