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...
An FMCW ultra-wideband radar concept for through-the-wall detection of human beings is presented. Propagation modeling through different types of walls and radar cross section measurements of human beings are given. Power budget and dynamic range are computed and discussed for different situations. The realized UWB FM-CW radar is presented and some fast trials of human beings tracking are shown. This...
A study of an ultrawideband frequency-modulated continuous-wave radar with an extended frequency sweep from 0.5 to 8 GHz is presented. It has been applied to through-the-wall human detection. This work presents the modeling of wall attenuation followed by real measurements. The radar system is presented, and trials of human being tracking are shown. This radar will enable large stand-off distance...
