时间反射镜（TRM）技术由于其在非均匀介质中的高分辨率，在声学和电磁学领域得到了广泛的应用。本文通过数值仿真，将该技术应用于超宽带穿墙雷达对抗中的目标成像。我们首先考虑的技术，以图像的目标背后的单层墙壁，然后扩展到多层墙壁。仿真结果报告了该算法的成像能力及其在TWR成像中的强大用途。关于图像的稳定性，我们调查的TRM图像的情况下，其中有一个与时间反转的正相和反相的墙壁之间的不匹配。在此同时对反投影成像算法进行了成像质量对比。最后得出了一些结论。
Time Reversal Mirror (TRM) technique, in the virtue of its high resolution in the heterogeneous media, has been widely applied in the area of acoustics and electromagnetics. In this paper, the technique is developed to imaging targets in the contest of ultra-wideband (UWB) through wall radar (TWR) through numerical simulation. We firstly consider the technique to image targets behind a single-layered wall and then extend to the multi-layered wall. The simulation results have reported the imaging capability of the algorithm and its powerful use for TWRimaging. For concerning the image stability, we investigate the TRM images for the case in which there is a mismatch between the walls associated with the forward and inverse phases of time reversal. The back projection imaging algorithm is compared here at the same time for a contrast of the imaging quality. Finally, some conclusions are drawn.
