ELECTROMAGNETIC SCATTERING BY ROUGH SURFACES WITH LARGE HEIGHTS AND SLOPES WITH APPLICATIONS TO MICROWAVE REMOTE SENSING OF ROUGH SURFACE OVER LAYERED MEDIA

In this paper, we study the bistatic re∞ection and transmission properties of random rough surface with large slope and large height. Method of Moment (MOM) is used to solve the surface integral equations for 2D rough surface scattering problem. The modeled rough surfaces are similar to random rectangular grating, so that there are large slopes on the surface. The motivation of the study is to analyze scattering by sastrugi surface in Polar Regions. The ridges on the sastrugi surface have heights of about 20cm. In microwave remote sensing of land at 5GHz, 10GHz, 19GHz and 37GHz, these heights are larger than wavelength. Next, we consider
