A high‐frequency ray analysis of the electromagnetic backscattering by a two‐dimensional ogive

Abstract

The electromagnetic backscattering from a two‐dimensional ogive is examined, including a mechanism‐by‐mechanism account for the scattered field. The uniform theory of diffraction is used in conjunction with a simple creeping wave representation to yield a solution which provides an accurate and continuous backscattering result for a wide range of ogive geometry parameters. Although not a rigorous derivation of higher‐order diffraction coefficients, this solution provides insight into the relative contributions of the various creeping waves which are generated and propagate around the two‐dimensional ogive. Comparisons with moment method (MM) calculations are used to demonstrate the range of applicability of this high‐frequency asymptotic solution.
