| 摘 要： | 为了解决由于点状体的绕射和倾斜界面造成的失真现象，本文从探地雷达偏移处理的基本原理出发，分别介绍了以射线理论为基础的绕射扫描偏移和以波动方程为出发点的克希霍夫积分偏移、有限差分偏移以及有限元偏移．随着计算机的高速发展，运算速度得到了明显提高，目前，以波动方程为基础的偏移方法逐渐占据了主导地位，由于它的高精度等很多优点受到了人们的欢迎．总结了各种偏移方法的优缺点和适用范围，为探地雷达进一步的偏移研究奠定了理论基础．

| Abstract: | For improving the resolution of geological interpretation,the fact profile data are required migration.Inthis paper we discussed the theory of migration processing of ground-penetrating radar and introduc the migrationmethod,including diffraction scan migration based on ray theory,Kirchhoff migration,finite difference migration andfinite element migration based on wave equation.With the development of the computer,the rate of operation is im-proved.Presently,the migration methods which are based wave equation holds the leading station gradually,and it iswidely accepted because of its strongpoint such as precision.The paper summarizs advantages and disadvantages ofeach migration methods,as a result,it became the theory foundation for farther research of migration of ground-pene-trating radar. |
