LARGE SCALE SIMULATIONS OF SCATTERING OF WAVES BY RANDOM ROUGH SURFACES WITH APPLICATIONS IN MICROWAVE REMOTE SENSING AND WIRELESS COMMUNICATIONS

Scattering by random rough surfaces has been studied by analytic methods such as the Kirchhoff method and the small perturbation method. Numerical solutions of Maxwell equations were formidable in the past because in order to truly represent natural random rough surfaces, the profile must have many peaks and valleys. This require sample surface area of hundred or even thousands of square wavelengths
