Depth-limited search applied to compute n-order reflections in the analysis of the RCS in large and complex targets

A new iterative algorithm able to consider multiple iterations between different flat surfaces, to compute efficiently the monostatic and/or bistatic radar cross section (RCS) of complex targets is presented. This method is based on a combination of several ray-tracing acceleration techniques as AZB and SVP algorithms together with uniformed search strategies as depth-limited search strategy, reducing the CPU time and memory resources.
