%X The dihedral corner reflector with wing and fuselage joint of aircraft is a very strong electromagnetic source in a wide angular range.But traditional RCS computation method is only suit for the ideal dihedral corner reflector.This paper adopts Geometrical Optics(GO)and Physical Optics(PO)methods to compute double and thrice bounce contributions of a rectangle dihedral corner reflector.And on the base of illumination width,a concept of Equivalent Illumination Area(EIA)is presented.Through the analysis of EIA,a modified computational method is given,which can analyze a dihedral corner reflector with arbitrary shape of planes and with shadow objects.To valid this method,RCS of wing and fuselage joints of a certain hypersonic vehicle is computed,and the result validates its correctness.
