摘要:

基于双程波动方程的逆时偏移相比于传统的单程波偏移,具有原理简单、成像精确且无倾角限制、适应任意复杂速度模型等诸多优点,在探地雷达(GPR)高精度成像领域得到广泛关注.本文首先回顾和总结了逆时偏移方法在GPR成像领域的研究现状及其存在的问题.然后,分别从多偏移距GPR数据的快速采集,复杂介质的GPR逆时偏移成像、成像条件的稳定性、成像效果的改善、计算效率的提高等方面介绍了GPR逆时偏移成像研究的最新进展及其具体的应用效果.最后对GPR逆时偏移成像的发展趋势进行了总结.

Abstract:

Due to the Reverse Time Migration (RTM) of the two-way wave equation has the advantages of simple principle, accurate imaging, no inclination limits and adapting to any complex velocity model compared with traditional Kirchhoff migration and one-way wave migration, it has been widely concerned in the high precision imaging of Ground Penetrating Radar (GPR). In this paper, we firstly review and summarize the research progress and existing problems of RTM in the field of GPR imaging. And then, new techniques for GPR RTM imaging such as multi-offset GPR data rapid acquisition, efficient simulation of electromagnetic field of complex media, stability of imaging condition, improvement of the imaging effect and calculation efficiency are discussed. Finally, the development trend of GPR reverse time migration imaging is summarized.

Key words: Ground Penetrating Radar(GPR), Reverse Time Migration(RTM), Imaging condition, Research trends
