克希霍夫积分偏移法在探地雷达图象处理中的应用

APPLICATION OF KIRCHHOFF INTEGRAL MIGRATION METHOD TO PROCESSING GPR IMAGE

由于探地雷达(GPR)剖面与反射地震剖面的相似性,用于处理反射地震剖面的偏移理论与方法,可以用于GPR图象的处理,文中介绍了克希霍夫(Kirchhoff)积分偏移法的基本原理及其在GPR图象处理中的应用,对已知地电模型的GPR记录进行了偏移处理,并给出了对两条实测GPR记录作偏移处理的实例,总结了偏移方法处理GPR图象的应用条件。

Owing to the similarity between GPR profile and reflection seismic one, the migration theory and method applied to processing seismic data can be used to process GPR data. The basic principle of Kirchhoff integral migration method is introduced and applied to processing GPR images. The modelling GPR profiles and field ones are migrated. Finally, the conditions are summarized for the application of migration method to processing GPR images.
