EM Scattering from Complez Targets above a Slightly Rough Surface
A hybrid approach which combines the four-path model with a quasi-image method is developed in this paper to deal with the high frequency EM scattering problems of complex targets located above a slightly rough surface. The computation process of the multipath scatterings in the four-path model is greatly simplified by using the image targets to treat the shadowing effects and a damped reffection coefficient to correct the scattered field of the rough surface. The effectiveness and efficiency of this method are verified by numerical results, which show that the proposed approach can be used to quickly and accurately evaluate the high frequency scattering from complex targets above a slightly rough surface.
