Research on Ground Penetrating Radar Migration Imaging Technology

Abstract

The ability of Ground penetrating radar (GPR) to estimate the shape and position of objects in target area is depends on the imaging technology. Migration image method was popular used in seismic wave detection technology, and now it is used in GPR electromagnetic wave detection technology. In this paper, three migration image methods: Finite Difference Time Domain (FDTD), Frequency Wave number, and Kirchhoff migration method are been discussed separately. By dealing with GPR simulation and experiment data, it shows that the seismic wave migration method used in GPR imaging is effectiveness and stability. At last, compare the imaging results of three migration methods, several useful conclusions are been given.
