摘　　要：基于矩量法,分析了目标单站雷达散射截面(RCS)的计算方法.当进行扫角计算时,平面波入射角度的变化只会对右端电压矩阵产生影响,左端阻抗矩阵不会发生变化.根据这一特点,提出了一种基于高斯消元法的单站RCS快速计算方法.对第1个角度,记录下消元过程,并将阻抗矩阵转换为乘积因子矩阵.在对其余角度的矩阵方程求解时,只需对变化的右端电压矩阵按照第1个角度的消元过程进行相应计算即可,从而加快了整体角度范围的单站RCS计算.The calculation method of monostatic radar cross section （RCS） is analyzed based on method of moment. When calculation of RCS is started by looping over angles, only the right voltage matrix is effected with the changes of the incidence wave. The left impedance matrix is not changed. Based on the characteristic, a new fast calculation method of monostatic RCS using Gauss elimination method is proposed. The elimination procedure is recorded when the monostatic RCS of the first angle is calculated, and the impedance matrix is transferred into product factors matrix. When the monostatic RCS of the other angles are calculated, only the right voltage matrix is calculated follow the elimination procedure of the first angle, thus the monostatic RCS calculating speed of the whole scale angels will be quickened greatly.
