Abstract
The ultra-wideband through-wall detection radar (UWB-TWDR) system is burgeoning and considered as one of the promising systems for rescue and military use. In this paper, the mechanism and structure of a simple and low-cost UWB-TWDR system are presented. Compared with previous systems, android based mobile devices were used to replace the traditional PC, making the system more portable and affordable for most users. In addition, correlation detectors were applied to simplify the circuit and further reduce the cost. The algorithm for locating and tracking during the process of acquiring and handling data from antennas was also discussed. Experimental results of our system showed a good performance in practical through-wall human detection.
