Abstract

Abstract:

The building of RCS calculation platform which includes many different RCS mechanisms is introduced.Considering that the huge computation of ray tracing is the bottleneck of the efficiency of the RCS calculation platform, a method for reducing the computation of ray tracing is given, which suggestsed the calculation of the coupling scattering areas only.The authors conduct a rough ray tracing before really tracing to identify the coupling scattering areas, and obtain some scattering distribution maps of arbitrary targets using this method.

Key words: radar , cross , section, , electronmagnetic , scattering, , couplingscattering, , ray , tracing, , pretracing
