摘　　要：将PNM方法 (ProgressiveNumericalMethod)与以RWG为基函数的矩量法(MoM )和AutoCAD自动电磁建模剖分技术相结合 ,来快速有效地分析三维任意形状的电大目标问题。数值实例和计算结果表明 ,PNM算法的引入可有效地节省计算资源和计算时间 ,而且计算精度较高 ,最终为快速分析电大目标的电磁兼容问题提供了一条新的有效途径。In this paper, PNM (Progressive Numerical Method ) is well combined with MoM on the base of RWG and AutoCAD to quickly analyze the scattering problem of three-dimensional perfectly conducting bodies of arbitrary shape. The numerical results are well agreed with that from conventional MoM. At the same time, PNM needs much less computational time and less EMS memory, and higher accuracy.
