An efficient approach to compute the RCS of complex targets considering multiple bounces

An approach for computing efficiently monostatic and/or bistatic radar cross section (RCS) of complex targets considering multiple bounces is presented. The approach is based on physical optics (PO), the equivalent currents method (ECM), geometrical optics (GO) and a new ray-tracing accelerating algorithm. The new tool is very efficient and save memory and resources computing the RCS considering different iterations. Monostatic or bistatic RCS of complex targets modelled by planar or parametric surfaces can be obtained. The program has its own facility to generate or modify an existing geometry.
