Abstract An efficient algorithm is present for improving the acceleration technique of the monostatic radar cross section (RCS) prediction based on monostatic bistatic equivalence principle for the shooting and bouncing ray (SBR) method. Using the monostatic bistatic principle, the time consumed by the monostatic RCS simulation can be greatly reduced since the ray tracing procedure of the SBR method is avoided for a lot of incident angles. However, the result of the monostatic RCS using the monostatic bistatic equivalence get worse in the case of multiple bounces in ray tracing. To remedy this disadvantage, parts of rays are chosen with a sophisticated algorithm to be traced in order to correct the phase and location of the ray tubes. Numerical results demonstrate that the present algorithm is efficient for the SBR method in analysis of electrical large objects. © 2011 Wiley Periodicals, Inc.
