Abstract

This paper is concerned with an analysis of back scattering of electromagnetic waves from a target moving along inhomogeneous random rough surfaces such as desert, sea surface and so on. First we introduce the discrete ray tracing method (DRTM), and second we apply this method to the back scattering problem in order to investigate the effect of the back scattering from inhomogeneous random rough surfaces on the radar cross section. Finally we show some numerical examples for various height deviation of the Gaussian type of rough surfaces. It is demonstrated numerically that the back scattering is dominated by the diffractions related to the reflections from the random rough surfaces.
