Ultra-wideband Frequency Modulated Continuous Wave synthetic aperture radar for Through-The-Wall localization

Abstract

In this paper we present the development and preliminary results of an ultra-wideband Frequency Modulated Continuous Wave (FMCW) Through-The-Wall (TTW) radar prototype built at ONERA in Toulouse, France. The radar operates between 0.5 and 8 GHz in three possible subbands: 0.5–2 GHz, 1–4 GHz or 2–8 GHz depending on the type of wall. The radar has been suscessfully tested in free space and trials with a cinder block wall are on going.
