| 摘 要： | 将时间反转镜成像技术和SAR成像技术相结合,通过理论分析和仿真实验将它应用到超宽带探地雷达成像中。实验采用了粗糙地面和电参数随机的泥土真实反映复杂探地环境。将相应的时间反转镜成像技术-SAR成像结果与时域后向投影成像算法进行了对比,结果显示,时间反转镜成像技术凭借其统计自平均特性和空时匹配滤波特性,能够为超宽带探地雷达系统提供更高分辨率的成像结果。

| Abstract: | Time reversal mirror(TRM) technique is based on the principle of reciprocity.This technique perfectly caters to the demands of detection range and resolution in the complex environment.Therefore,it attracts more and more attention recently.This paper combines the TRM technique with SAR(synthetic aperture radar) imaging technique,and introduces it to the ultra-wideband ground penetrating radar(UWB-GPR) system through numerical simulation and theoretical analysis.For real applications,we consider the detectio... |
