摘　　要：提出了一种快速求解目标单站RCS的有效算法。传统的矩量法在求解目标单站RCS时,对于每一个激励基函数与缩减矩阵均需要重新构造,计算十分耗时。因此,本文提出了一种基于奇异值分解的特征基函数法,该方法通过奇异值分解来减少基函数生成数目,且不会降低求解的精度,数值算例证明了方法的有效性。An efficient algorithm for solving monostatic RCS of objects is proposed. In traditional method of moment,the solu- tion of monostatic RCS should reconstructed basic functions and reduced matrix for every excitation, the computation is time-con- suming.Therefore, a characteristic basic function method which based on the singular value decomposition is proposed in this pa- per.This method reduces the number of basis functions by singular value decomposition, and without compromise to the accuracy of the solution. Numerical examples demonstrate the efficiency of the proposed method.
