Abstract

The slightly rough facet model has often been used to describe radar scattering from two-scale rough surfaces. Moment method scattering calculations are used to investigate the validity of a theoretical method for determining the maximum allowable facet sizes. The method is shown to give accurate facet sizes for rough surfaces with large-scale curvatures comparable to that expected on the ocean surface at angles of incidence where the traditional two-scale scattering model has proved to be valid
