| 摘 要： | 在探地雷达（Ground-Penetrating Radar,简称GPR）剖面中，由于绕射波的存在，使得资料的处理解释十分困难，其结果的准确性与真实度也会降低。针对这一问题，作者提出了探地雷达有限差分波动方程偏移法，首先进行了理论模型的实验分析，在此基础上我们对实测GPR剖面资料进行分析处理，取得了较好的成果。

| Abstract: | Due to the interference of diffraction waves, the processing and interpretation of Ground Penetrating radar(GPR) data will become difficult and the precision and reality of their results will be also reduced. Being directed against this problem, a method of the wave equation migration with finite difference to eliminate the diffraction waves in GPR data is derived in this paper. Based on the model testing and analyzing, the good results of processing and analyzing are achieved for a field GPR data using the method. |
