摘　　要：在有限的硬件条件下，作为电大尺寸目标的标准靶标RCS仿真计算是一个难点问题。在建立标准靶标几何模型并对其进行前置处理的基础上，以物理光学（PO）和一致性绕射理论（UTD）等为基础，综合多种算法的优点并将其混合使用，再加入边缘修正、尖劈修正，计入爬行波影响等，解决了电大尺寸目标的RCS计算问题。通过将仿真计算结果与典型算例以及护卫舰缩比模型测量值的比较，证明了计算方法的有效性和准确性。As an electrically large object, the simulation method for radar cross section （RCS） of criterion target for anti-ship missile shooting is a difficult problem. The geometrical model of criterion target which used a certain main force frigate overseas as prototype was founded. With some pretreatment and on the basis of PO and UTD, a great deal theory was combined along with edge correction, wedge correction and crawl wave calculating, and the problem of RCS calculation and simulation of electrically large objects was solved Through calculating the RCS of calibration objects and reduced frigate model, and comparing them with the actual measurement results, it was proved that the method adopted was effective and accurate
