Multi-reflection Calculation of RCS and Programing
-
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.Abstract: 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.
