Zpatch. A high frequency bistatic signature prediction code

This paper describes a high frequency bistatic radar cross section (RCS) prediction computer code called "Zpatch" which is based on the high frequency technique of shooting and bouncing rays. A modern computer graphics technique called "z-buffering" is used for rapid solution of the line-of-sight hidden surface problem. Zpatch is capable of generating monostatic and bistatic RCS results for complex, electrically large targets in several existing and popular CAD formats.
