Results are presented to show that hard-to-predict wide-aspect-angle radar cross-section (RCS) results from a circular disk are primarily accounted for by second, and possibly higher, order diffraction coefficients of the uniformed geometric theory of diffraction (GTD). These yield a significant improvement over the first order predictions, which are polarization independent, and predict backscattered fields which compare favorably with the experimental results.
