摘要
介绍目标ＲＣＳ分析计算中多次散射的计算方法，计算多次散射时主要考虑面元面元之间的相互作用，计算过程采用几何光学法（ＧＯ）、物理光学法（ＰＯ），在总后向ＲＣＳ计算中还运用了等效电磁流法．同时，文中讨论计算多次散射的程序实现技术．最后，给出计算例子，考虑多次散射时总的后向ＲＣＳ计算结果与前人发表的实验结果相吻合．
The method to calculate the multi reflection in RCS is discussed. It mainly considered the interaction of facet and facet by using the geography optics(GO) and physical optics(PO) in calculation . In the calculation of the total RCS, we also use the equivalent currents method(ECM) to calculate the contribution of edge . It also gives the method of how to complete the multi reflection calculation by program . Finally, some examples calculated by this program are given . Results computed are in good agreement with experimental data previously.
