Abstract

Abstract

As a new type of ground detection technology, Ground Penetrating Radar (GPR) has advantages of high resolution and fast survey and no damage in detection, especially in the exploration of shallow active fault. However, the result image of GPR is not consistent with the objective facts in undulated areas. This paper presents a new method to correct the topographic distortion of GPR image:GPR and GPS are combined to collect and record data at the same time, achieving time synchronization between the GPR data and GPS data. Specifically, through time shifting and linear interpolation method, taking a standard level for reference surface, converting the time-depth of GPR data, finally achieving topographic correction. Contrast the original GPR image and adjusted GPR image, it shows that the method can correctly express the distribution characteristics of underground medium, and it is helpful to interpret and position the underground target, especially in the shallow active fault detection program.
