摘要
为分析大型涂层体隐身目标的RCS提出了一种快速单元级矢量有限元/自适应多层快速多极子算法,这种算法可实现大型复杂目标雷达散射截面的快速计算,同时提出了一种基于矢量网络分析仪测量目标雷达散射截面的测量系统方案和方法.数值与实验结果说明了方法的有效性.
A fast algorithm via element level vector finite element method(ELVFEM) and adaptive multilevel fast multipole algorithm(AMLFMA) is introduced for the RCS analysis of electrically large coated scatters.A system and method for RCS measurement in microwave anechoic chamber is presented.The numerical and experiment results show the effectiveness of the presented method.
