摘　　要：用三角网格模拟金属载体表面,应用矩量法求出天线载体网格上的电流分布,据此研究在该金属载体影响下的雷达散射截面(RCS)计算。计算线面结合部分时,利用了Costa函数,减少了内存需求和计算量。数值结果证明了该方法的正确性。In this paper, the surface of metal is meshed with triangular patches, and the current distribution on the wire-grid model is attained based on Method of Moment, then we can acquire the RCS with the influence of the metal. It uses the Costa Function to calculate the RCS of connect position between wire antennas and metal plate. This method requires small memory with a high precision. Several examples are given to testify the validity of the presented method.

关 键 词：线面结构 矩量法 雷达散射截面
