Abstract
In this, work, a uniform high-frequency solution based on an asymptotic analysis of the physical optics (PO) integral for a conducting surface is presented for backscattering of plane waves for a discontinuity in curvature for arbitrary surfaces. This approximation is valid near caustics. Far from caustics, a solution derived from the uniform theory of diffraction (UTD) is used. The results of computer code, which demonstrate the accuracy of this technique, are presented
