三面角反射器的高频电磁散射分析

High-Frequency Electromagnetic Scattering by a Square Trihedral Corner Reflector

在物理光学（PO）和几何光学基础上，利用区域投影（AP）方法导出了一种新的高频混合方法－区域投影／物理光学（AP／PO）方法。应用AP／PO方法计算了三面角反射器的雷达截面（RCS）．计算结果与用FDTD方法得到的结果有很好的一致性。

A novel hybrid high-frequence method of area projection/physical optics (AP/PO)technique is derived on the basis of physical optics (PO) and geometrical optics with area projection (AP) method used. RCS of a square trihedral corner reflector is calculated with the AP/PO method.The AP/PO results is in good agreement with those obtained by FDTD method.
