Abstract :
A combination of acceleration techniques to compute the RCS (radar cross section) of complex targets is presented. The approach is based on the application of the angular Z-buffer (AZB) algorithm together with the SVP (space volumetric partitioning) algorithm, for electrically large and complex bodies modeled by a high number of flat and/or curved surfaces.
