Abstract

The high-frequency method for solving the Radar Cross Section (RCS) of Terahertz conductive targets in free space is presented in this paper. Consider the environment of free space, the free space physical optics integral equation is deduced by introducing the free space Green’s function into the Physical Optics (PO) method. Combined with the GRaphical-Electromagnetic COmputing (GRECO) method, the shadow regions are eliminated quickly and the geometry information is attained by reading the color and depths of each pixel. The RCS of Terahertz conductive targets can be exactly calculated in free space. The numerical results show that this method is efficient and accurate.
