High-frequency method for scattering from electrically large conductive targets in half-space

The high-frequency method for solving the scattering of electrically large conductive targets in half-space is presented in this letter. The half-space physical optics method is deduced by introducing the half-space Green's function into the conventional physical optics method. Combined with the graphical-electromagnetic computing method, the radar cross-section of conductive targets can be calculated in half-space. The numerical results show that this method is efficient and accurate.
