Bistatic multiple scattering from randomly rough surfaces

The contribution of bistatic multiple scattering from randomly rough surfaces is studied. A model with consideration of multiple surface scattering for bistatic surface scattering from a randomly very rough surface is developed on an approximation of a pair of integral equations. Without the consideration of multiple surface scattering, a considerable difference between the measured data and theoretical estimation exists, especially from very rough surfaces. Comparisons of model prediction with and without the contributions of multiple scattering from rough surfaces, are shown together with comparisons of model prediction with measured data.
