摘　　要：本文采用一致性几何绕射理论和物理光学法分析了有限长大尺寸完纯导体圆柱的散射特性。在绕射区,我们考虑了一阶和二阶绕射的贡献,在镜反射方向附近,作了驻相法近似,由此得到的一些有用的数值结果与实际测量所得到的结果吻合较好。Using uniform geometrical theory of diffraction (UGTD) and physical optics methed (POM), the scattering characteristics of a large prfectly conducting finite length circular cylinder are presented here. First - and second-order diffractions are included, while stationary approximations are used in the vicinities of specular reflecting directions. The measurements are also made, and the experimental results agree with the theoretical ones very well.
