Through-the-wall radar using multiple UWB antennas

In this paper, we present a study of short range radar for through-the-wall detection and tracking of human beings. New concepts envisaged here are based on an Ultra Wide Band (UWB) waveform and on the use of numerous separated antennas. A full wave 2D simulator using the FDTD method has been performed in order to deliver synthetic data for studying signal processing algorithms. These algorithms, although well known in some other contexts, are here applied to UWB TTW imaging and detection and some quasi real time formulations are proposed. Results are presented on a test configuration computed by the simulator.
