在矩量法(MOM)的基础上，采用混合场积分方程(CFIE)结合累进迭代的数值方法(PNM)研究了电大尺寸目标电磁散射问题。目标被分成一些小区域，因此缩小了所需要求逆的矩阵的大小并且减少了计算时间。数值模拟计算了理想导电的圆柱，矩形柱的表面电流分布。所得的结果和一般分域基矩量法的结果以及圆柱的理论计算结果吻合得很好，说明了本文方法的有效性。

Based on the method of moment, the object is divided into a number of small regions. Using combine field integral equation and progressive iterative numerical method, the size of method of moment system matrix that need to be inverted and the computational time can be greatly reduced. The distributions of electric current on the 2D conductive circular cylinder and rectangle cylinder are calculated respectively by the method in this paper. The results are in good agreement with those from general method of moment and the analytical solution. The effectiveness of the proposed method is demonstrated.
