Multiple Stationary Human Targets Localization in Through-the-wall UWB MIMO Radar

Stationary human target localization is a key issue in through-the-wall sensing applications. When there are multiple stationary human targets, wrong data association may result in localization of false alarms. This paper proposes an approach of multiple stationary targets localization based on data association using UWB MIMO radar with one transmitting and two receiving antennas. First, the number and distances of stationary human targets are detected on each channel separately, then correlation coefficient matrix is introduced to evaluate the association probability of targets from different channels, finally the targets are located with no artifacts. Simulation and experimental results verified the superiority of the proposed approach.
