Exploitation of polarimetry in short range 3D UWB-radar object imaging

Abstract

This paper deals with a 3D bi-static, fully-polarimetric Ultrawideband (UWB) imaging system for short range applications. The exploitation of polarization diversity provides valuable supplemental information compared to mono-polarized sensing techniques. This polarization diversity gain is utilized for a quad-polarized UWB-Radar system for the imaging of a complex shaped 3D Object with corners as well as edges. For a full perspective of the object the sensors provide circumnavigation to extract entirely all stereoscopic distributed polarimetric scattering centres. The experimental validation is carried out with a pair of two tapered slot line Vivaldi antennas both integrated in a conical shaped teflon rod and an M-sequence Radar device.
