摘要
利用物理光学法计算任意入射方向下材料涂覆非正交金属二面角反射器的后向散射,考虑了1次、2次和3次反射的贡献.通过对材料参数以及二面角的合理优化,可将金属正交二面角反射器的后向RCS减小至期望的水平.与矩量法的计算结果比较表明,该方法可以较好地预测二面角反射器后向RCS的变化趋势.
Method of physical optics is used to calculate the backscattering cross section of nonorthogonal dihedral corner reflectors coated by radar absorbing materials (RAM), illuminated in an arbitrary direction. Singly, doubly, and triply reflected contributions are considered. The results are then compared with those applying the method of moment, which shows that the trend of backscattering cross section of the dihedral corner reflector can be accurately predicted with this method.
