Sy. Wang et Sk. Jeng, A COMPACT RCS FORMULA FOR A DIHEDRAL CORNER REFLECTOR AT ARBITRARY ASPECT ANGLES, IEEE transactions on antennas and propagation, 46(7), 1998, pp. 1112-1113
A compact closed-form formula for the RCS of a perfectly conducting ri
ght dihedral corner reflector at arbitrary aspect angles is presented.
The approach is based on a combination of ray tracing, physical optic
s (PO), and the physical theory of diffraction (PTD). There is good ag
reement between the results obtained using the closed-form formula and
those obtained by the shooting and bouncing rays (SBR) technique.
