The paper presents several improvements in ray-tracing acceleration techniques to compute diffraction and doubles and triples effects in the RCS (radar cross section) as fast as possible and minimize the use of computer memory. 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 modelled by a high number of flat and/or curved surfaces.
