It has been shown that PO in combination with GO has relatively large limitations when calculating RCS for objects where interactions occur between different parts of the object. A method, PO-PO has been developed to correct the errors occurring when using physical optics together with geometrical optics to calculate multiple reflections. The method has been used to calculate the RCS from a 100 degree dihedral. The results show good agreement with calculations made with the method of moments for vertical polarization which makes the method useful in calculating RCS.
