Kirchoff Migration Algorithm for Ground Penetrating Radar Data

摘要

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.
