Abstract

The scattering of electromagnetic waves from random rough surfaces near the grazing incident problem is of widespread interest in various physical situations, in particular coastal and shipborne radar backscatter. It is, however, a very difficult problem still awaiting a satisfactory analytical solution. Two of the features which have been seen experimentally and yet have not been explained analytically are sea spikes, and unexpectedly large hh/vv scattering cross section compared to the analytical solutions available. In this paper we present a numerical study of backscatter cross section for the above situation. The numerical calculation was done using the Petit method, which unlike the better known method of moments (MOM), allows calculation to be done for the case of large angle incidence.
