在物理光学方法基础上，结合几何光学方法和射线跟踪方法，导出一种能有效计算复杂目标多次散射的高频混合方法一区域投影物理光学方法（AP／PO）。为验证方法的有效性，应用AP／PO方法计算了角反射器和相互垂直的两个导体板的雷达截面，计算结果与测量结果有很好的一致性。通过对某飞机模型RCS的计算及与实验数据对比，进一步证明AP／PO方法适用于复杂目标多次散射的计算。
Based on the physical optics method, combined with the geometrical optics method and the ray tracing method, a high-frequency hybrid method-area projection physics optics method (AP / PO) that can effectively calculate the multiple scattering of complex targets is derived. In order to verify the effectiveness of the method, the radar cross sections of corner reflectors and two conductor plates perpendicular to each other were calculated by using the AP / PO method. The calculated results are in good agreement with the measured results. By comparing the RCS of an aircraft model with the experimental data, the AP / PO method is further proved to be suitable for the calculation of complex target multipath scattering.
