摘要

目标的形状和位置估计是探地雷达中的一个重要问题。地震技术领域的偏移方法是对目标进行定位和重塑的有效方法。Kirchoff偏移法是基于电磁波方程的。这是一种精确的计算方法。Kirchoff偏移法对不同的电磁波水平和垂直速度具有广泛的适应性,且计算时间可以接受。本文首先介绍了偏移成像原理,然后讨论了Kirchoff偏移方法。通过对探地雷达模拟图像和实验图像的处理,证明了基霍夫偏移方法在探地雷达成像中的有效性和稳定性。

Kirchoff Migration Algorithm for Ground Penetrating Radar Data
Estimation the shape and position of the objects is an important subject in ground penetrating radar (GPR). Migration method in domain of seismic techniques is effective to locate and reshape the objects. Kirchoff migration method is based on electromagnetic wave equation. It is an accurate calculation method. Kirchoff migration method has widely adaptabilities with different horizontal and vertical velocity of electromagnetic wave, and the computation time is acceptable. In this paper, migration imaging principle is been introduced at first, then Kirchoff migration method is been discussed. By dealing with GPR simulation and experiment image, it shows that the Kirchoff Migration method used in GPR imaging is effectiveness and stability.
