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.
Keywords: electromagnetic wave, scattering, structure, radar cross section.
