摘要

Kirchhoff偏移在应用地球物理学中将地震数据转换为地质层图像方面起着重要作用。本文将基尔霍夫偏移应用于高频电磁法确定探地雷达速度模型的情况。利用Ramac X3M在胡志明市采集的500 MHz频率GPR原始数据，建立了一组不同速度的Kirchhoff迁移到速度模型，对其进行了处理。分析了一个衍射案例的迁移结果，选择了最佳速度。在两种情况下，从基尔霍夫迁移中选择的最佳速度被认为是中等环境速度。

Kirchhoff migration for specifying velocity model in ground penetrating radar method

The Kirchhoff migration plays an important role in converting seismic data into images of geological layers according to viewpoint in the applied geophysics. In this paper, the application of the Kirchhoff migration was used in the case of the high frequency electromagnetic method for specifying GPR velocity model. The measurements of raw GPR data collected by Ramac X3M with 500 MHz frequency in HoChiMinh city were processed on the basis of the Kirchhoff migration to velocity model by establishing a set of different velocities. The migrated results of a diffraction case were analyzed to choose the optimal velocity. The optimal velocities of being chosen from Kirchhoff migration in two cases were considered medium environment velocities.
