摘　　要：提出了一种分析导体目标电磁散射特性的有效数值方法,该方法以矩量法为基础,将自适应交叉近似算法应用于远场组阻抗矩阵的低秩压缩计算,并且结合等效偶极子法加速抽取阻抗矩阵元素的填充。与传统矩量法相比,计算时间和内存消耗都得到了有效缩减,数值结果证明了该方法的精确性和有效性。An efficient numerical approach is presented to analyze the electromagnetic scattering characteristics from conducting targets based on the Method of Moments（Mo M）in conjunction with the Adaptive Cross Approximation（ACA）algorithm. The ACA algorithm is applied to computing compressed forms of low rank block of far-field group impedance matrix, and the extracted impedance matrix is also accelerated filling by Equivalent Dipole Moment（EDM）method. The computational time and memory consumption are reduced significantly compared with the Mo M. Numerical results demonstrate that the proposed method has very good accuracy and efficiency.
