摘　　要：文章开展基于瞬时相位信息提取的探地雷达成像研究。在对瞬态信号分析方法的研究基础上,提出一种基于瞬态相位信息提取的雷达地下目标成像,通过提取反射信号中的相位信息生成的二维雷达相位图,在目标位置形成的轨迹具有更锐利的边缘,提高雷达成像中目标的辨识度,有利于提高地下目标估计和距离探测的准确性。GPR imaging based on instantaneous phase information extraction is investigated in this paper. With the help of transient signal analysis method, we proposed a new method of GPR imaging based on transient phase information extraction. By extracting the phase information of radar signal, two-dimensional radar phase images are generated with sharper edges at the target positions compared to the traditional two-dimensional amplitude radar images. The improved the recognition of the target in radar imaging is very helpful for better underground target estimation and distance detection.
