Po analysis for RCS of nonorthogonal dihedral corner reflectors coated by RAM

The backscattering radar cross section (RCS) of nonorthogonal dihedral corner reflectors coated by RAM (radar absorbing materials) formulated the method of PO (physical optics), where singly. doubly, and triply reflected contributions are considered. The final expressions are analytical and allow for the incidence nonperpendicular to the fold axis of reflector. results are compared with ones of MoM (method of mornent), which shows the trend backscatter the corner reflector can be this method.
