Abstract

The near-axial backscattering from a finite cone is studied using the equivalent current concept based on the uniform geometrical theory of diffraction (UTD). The creeping waves associated with the conical surface are also incorporated into the equivalent current technique. The contributions from the creeping waves are significant for the oblique-incidence case. There is evidence to speculate that the poorer agreement between the previously calculated results and the measured data for the vertically polarized backscattering is probably a result of the omission of the creeping wave contribution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
