Bistatic Cross Section Computation of Complex Radar Targets in High Frequency Region by Using GRECO Method and Virtual Reality

通过应用单双站等效原理，将目前分析高频区复杂目标后向 Ｒ Ｃ Ｓ 最有效方法之一的图形电磁计算（ Ｇ Ｒ Ｅ Ｃ Ｏ） 技术拓广到计算双站 Ｒ Ｃ Ｓ领域，并给出了与实验结果符合良好的标准体与复杂目标的虚拟现实实例的单双站 Ｒ Ｃ Ｓ计算曲线。

Graphical Electromagnetic Computing (GRECO) is recognized as one of the most valuable methods of the RCS (Radar Cross Section) computation for the high frequency region.This paper shows satisfied results of computing monostatic and bistatic RCS in the high frequency region by using the hybrid method of GRECO and Monostatic bistatic Equivalence Theorem.At the same time,it gives monostatic and bistatic RCS curves of standard body and a complex target for a practical virtual reality,which satisfied the meausred results.The results have practical engineering value.
