High-frequency analysis of scattering from complex targets in half space

The high-frequency method for solving the scattering from electrically large conductive targets in half space is presented in this paper. The high-frequency method is deduced by introducing the half-space Green's function into the conventional method of physical optics, method of equivalent currents. Combined with the graphicalelectromagnetic computing method and ray tracing technique that account for shadowing and multiple scattering in half space, one may calculate the radar cross-section of a conductive target object in a half space. The numerical results show that this method is efficient and accurate.
