Target configuration effect on wave scattering in random media with horizontal polarization

Abstract

In a previous study, the radar cross-section (RCS) was shown to be influenced largely by the curvature of the illumination region of the target. Scattering data from smooth concave–convex contours reveals the obvious impact of specular reflections on the behavior of RCS. This effect needs to be investigated more especially with relatively complex surfaces. Here, we work on a numerical calculation of the RCS and analyze its characteristics with different target configurations including complexity and size. We postulate a concave illumination region and consider targets that are taking large sizes of about five wavelengths. In this communication, we assume wave propagation and scattering from targets in free space and random medium with consideration of horizontal incident wave polarization.
