| Some questions are discussed in this paper about electromagnetic scattering modeling of radar targets and computing for bistatic RCS for high frequency region. For bistatic RCS situation in small bistatic angles, the 搈onostatic-bistatic equivalence theorem?which gives a method of estimating the bistatic cross section from known monostatic cross section was used to obtain the bistatic RCS in small bistatic angles. 揋raphical Electromagnetic Computing (GRECO)?is recognized as one of the most valuable method of RCS computation for the high-frequency region, but to the low RCS target, the effect of traveling wave or creeping wave is remarkable and larger than that of facets and wedges in some cases. This paper shows some satisfied results by using the hybrid method of GRECO and traveling wave theory or creeping wave theory. |
