估计物体的形状和位置是探地雷达（GPR）中的一个重要课题。偏移法是地震波探测技术中常用的对物体进行定位和重塑的方法。时域有限差分(FDTD)偏移方法得到广泛应用，不仅因为迭代方法可以节省计算机内存，而且因为它对不同的电磁波水平速度和垂直速度很敏感。本文首先介绍了偏移成像原理，然后讨论了FDTD偏移方法。通过对探地雷达仿真和实验图像的处理，表明FDTD偏移方法在探地雷达成像中的有效性和稳定性。
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.
