Ground Penetrating Radar Imaging Based on FDTD Migration Method
Abstract:
Estimation the shape and position of the objects is an important subject in ground penetrating radar(GPR). Migration method is popular used in seismic wave detection technology to locate and reshape the objects. Finite difference time domain(FDTD) migration method is widely used not only because the iterative method can save the computer memory but also because it is sensitive with different horizontal velocity and vertical velocity of electromagnetic wave. In this paper, migration imaging principle is been introduced at first, then FDTD migration method is been discussed. By dealing with GPR simulation and experiment image, it shows that the FDTD Migration method used in GPR imaging is effectiveness and stability.
