摘要
在探地雷达的实测资料中 ,由于绕射波的存在导致了地下结构图象显示不清。根据电磁波与弹性波传播的相似性 ,本文将地震资料处理的偏移算法 (即基于标量波动方程的逆时偏移算法 )运用到探地雷达的资料处理中。结果显示 ,绕射波得到了很好的归位 ,反射体的连续性得到了加强 。
In ground-penetrating radar profile,the image of subsurface structure is distorted and unfocused due to diffractions.According to the comparability propagation between the electromagnetic wave and the elastic body wave,the author apply the migration algorithms of the seismic data into the radar data processing,that is to say the reverse-time migration based on the scalar wave equation.The result of the migration reveals that the diffraction wave goes back to the original place and the reflector continuity is enhanced.It provides a possibility to improve the resolution of geological interpretation.
