| 摘 要： | 为了求解复杂目标的雷达散射截面，通过把复杂电大尺寸目标剖分成若干电小尺寸的三角形面元，使每个面元满足远场条件。采用物理光学法对可见区域小三角面元进行积分求和，利用等效电磁流法对三角面元特征量及其劈边缘进行积分之和，并应用Gordon解析式求解整个复杂目标RCS。通过仿真计算对其结果进行对比分析，该方法计算出来的复杂目标RCS是有效的、准确的，可以作为实际工程应用的一种方法。

| Abstract: | In order to solve the complex target of radar cross-section （RCS）, this paper divides the large complex target into a number of small triangular polygon segments, making each segment to meet the far field conditions. This paper solves the entire complex goal of RCS by the physical optics method （P0） to integral the characteristics of the small triangle polygon segment in lighting district, and by the equivalent current method（ECM） to integral the edge of the small triangle polygon segment, and also with the Gordon analysis of their results, the complex target RCS which computed by the method is not only valid but also accurate, and more importantly this method can be used as a way of practical engineering applications. |
