Abstract:
A new radar cross section (RCS) prediction technique based on beam tracing is presented. The incident plane wave is modeled as a set of trigonal ray tubes, and each ray tube is traced and recursively subdivided as its reflection aspect. The calculation time of the proposed method is independent of target size. The proposed method provides accurate solutions and is efficient for RCS analysis of electrically large targets.
