High-frequency analysis on scattering from complex conductive 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 graphical-electromagnetic computing method and ray tracing technique that account for shadowing, multiple scattering in half space, one may calculate the radar cross-section of a conductive targets object in a half space. The numerical results show that this method is efficient and accurate.
