Description
Summary:This paper is concerned with an analysis of the back scattering of an electromagnetic wave by a target moving along just above a random rough surface such as desert, hilly terrain, sea surface and so on. First we introduce the discrete ray tracing method (DRTM) for the field analysis of back scattering. Second we investigate the effect of clutter due to back scattering from the random rough surface on the radar cross section (RCS) of the target. Finally we show some numerical examples for back scattering from a target above a Gaussian type of random rough surface with arbitrary height deviation and correlation length. It is demonstrated that the clutter is predominant in the back scattering and it is mainly caused by the diffraction related to reflection from the random rough surface.
