摘    要:本文提出的物理光学迭代法的子域连接法不但适用对电大尺寸一般腔体雷达截面的计算,而且能有效降低数值计算时间.它是将腔体分成若干个子腔体,每个子腔体用物理光学迭代法分析,子腔体之间电磁耦合通过对整个腔体循环迭代计入.数值结果验证了本文方法的正确性.

关 键 词:腔体  物理光学迭代法  子域法  雷达截面

Abstract:In this paper,a subdomains splicing technique for iterative physical optics (IPO) approach has been presented.It can be applied to calculate the radar cross section (RCS) of electrically large size cavities widely,and reduce the time of numerical computation greatly.The new approach is to split a cavity into some subcavities and to analyze each subcavity with IPO approach.The electromagnetic coupling of each subcavity has been considered by a loop iterative in the whole cavity.Some numerical results have been shown to verify the present approach.
Keywords:cavity  iterative physical optics  subdomain method  radar cross section
