| 摘 要： | 将时间反转(Time Reversal,TR)技术与阵列成像技术相结合,通过数值仿真研究了该技术在超宽带穿墙雷达(Through-the-Wall-Radar,TWR)探测中的应用。仿真分别考虑了单层和多层墙体环境下隐蔽的单目标和多目标探测问题,并将相应的时间反转成像与改进的后向投影(Improved Back Projection,IBP)算法成像进行了对比。结果显示,时间反转技术能够为超宽带穿墙雷达探测系统提供更高分辨率的探测结果。

| Abstract: | By combining with array imaging technique,the application of Time Reversal（TR） technique in Ultra-Wideband Through-the-Wall Radar（UWB-TWR） system is introduced through numerical simulation.TR detection for one or more concealed targets is considered in the environments of single-and multi-layered walls.The corresponding TRM images are compared with those of Improved Back Projection（IBP） method.The results show that TRM technique can provide the UWB-TWR system with higher resolution of imaging. |
