Through-Wall Moving Target Tracking Algorithm in Multipath Using UWB Radar

Through-wall moving target tracking is an essential part of applications with the purpose of sensing moving human in the sealed building. However, the major challenge stems from the multipath effect in the actual environment, which creates errors in the range delay of moving target. In this letter, an effective through-wall moving target tracking algorithm in multipath is proposed. This method based on the correlation of human motion can restore and estimate the range delay of the moving target in the strong multipath interference. Both simulation and experiment results indicate that the proposed method can not only suppress multipath but also smooth the trajectory.
