Abstract

It has been shown that the backscattered fields from a triangular corner reflector can be predicted using geometrical theory of diffraction (GTD) and physical theory of diffraction (PTD) techniques. The two theories are nearly identical far from the forward region, but the GTD method begins to fail near the forward region. The theories can more accurately predict the fine details of the experimental results if higher order diffractions are included. Because the structure of the corner reflector is comprised of flat polygonal plates, the integrations associated with physical optics (PO) and PTD are overcome by performing them in closed form. As a result, PO and PTD techniques are more suitable for this and similar structures, and lead to more accurate results when compared with experimental data.
