摘　　要：利用几何光学和物理光学(GO+PO)的方法计算带有活动板一类角反射器的高频散射。给出了执行多次反射计算的一般流程,推导了计算多次反射的物理光学积分公式。对侧翻板型和上翻板型两种三面角反射器的雷达散射截面(RCS)进行计算,获得与测量结果较好的一致性。通过对常规三面角反射器和带活动板的三面角反射器后向散射特性的比较和分析,得出一些有利于优化设计的结论。The approach of geometric optics and physical optics （GO＋PO） is applied to the computation of the high-frequency scattering by the corner reflectors with movable plates. The general flow of the multiple-bounce is giv-en and the physical optical integral equation for multiple-bounce is deduced. The results of trihedral corner reflectors with movable side plates and top plate are gained and RCS in well accordance with the measurements. After the com-parisons of these two kinds of reflectors with a common one,some valuable conclusions are drawn.
