摘要

Based on the Finite-Difference TimeDomain (FDTD) method, this paper presents a novel Time Reversal (TR) algorithm for multiple targets or moving object detection. Two numerical experiments are carried out by the FiniteDifference Time-Domain (FDTD) programs. The results confirm that the proposed TR algorithm could detect multiple targets effectively and track the moving object accurately. The re-focusing waves are very similar with the excitation signal, which can be applied in communications.
