A DETECTION AND LOCALIZATION ALGORITHM FOR MOVING TARGETS BEHIND WALLS BASED ON ONE TRANSMITTER-TWO RECEIVER CONFIGURATION

2017    Yilmaz, Betul; Ozdemir, Caner

In this paper, we introduce a simple; but an effective algorithm to detect and image the precise location of moving targets behind obstacles based on one-transmitter and two-receiver configuration. The problem geometry together with the formulation details of the algorithm are given. The performance of the algorithm is first evaluated by synthesizing a numerical scenario that is simulated by moving ideal scatterers. Then, the success and the validity of the algorithm are being assessed by an error analysis study that calculates the error associated by the approximations. The algorithm is tested with measured data obtained by an experimental set-up for detecting a human movement behind the wall. Resultant two-dimensional consecutive images indicate that this algorithm can be effectively used for pinpointing the moving targets in TWR or similar through-the-obstacle radar applications with good fidelity.
