Bidimensional radar signature of simple geometries

Abstract

Radar targets are objects with complex geometries carrying information about the simple components, if the wavelength is comparable with their linear dimension. Two basic geometries, found at aircrafts, are investigated in this paper: a dihedral and a cylinder. The finite thickness of these objects was considered, as well. The Radar cross section was assessed by using two-dimensional signals with linear modulation covering a discrete frequency band for about two octaves. The results, obtained by simulation, show that it may be possible to detect the specific electromagnetic signatures of the different kind of aircrafts by spatial and temporal signal processing.
