| 摘 要： | 将共轭梯度－快速多极子法应用于散射截面的求解中。对二维散射体射截面的求角作了较详细的讨论，提出了相应的参数及迭代终止判据的选取方法，使得算法在求解电大尺寸散射体散射截面时，能更有较地缩短计算时间。

| Abstract: | In this paper, CG FMM is applied for the solution of RCS in electromagnetic scattering problems. Careful discussion is made on the RCS solutions for various 2 D scatterers. Several parameters and the iterative terminate criterion have been presented. Comparing with other methods, this algorithm has more advantage when electrically large objects are concerned. |
