Radar cross section study from wave scattering structures

Abstract

Radar remote sensing deals with the extraction of object information from electromagnetic wave parameters. To fully exploit the potential of acquiring quantitative information requires a detailed description of the microwaves scattering. The research on this topic was mostly centered on far-field analysis that assumes an incident plane wave, computation of its scattered field, and evaluation of the radar cross section. However, under certain practical conditions, the far-field analysis is not valid and a near-field analysis is necessary. In this paper, we have given a full analysis of the near-field of a wedge structure due to an incident wave field from a line source or a plane wave. The far-field pattern, for the case of a line source exciting the structure, is also analyzed.
