Abstract
The effects of non-orthogonality of trihedral corner reflectors are si gnificant when the reflector dimensions are large compared to the wave length. Therefore, a high frequency approach is adopted combining geom etrical and physical optics. A simple frequency dependent relationship is proposed for the maximum cross-section loss due to a given angular uncertainty. Polarization purity and phase stability are also address ed.
