文摘This paper begins with the basic principles of finite-difference migration and diffraction scan migration,and then compares the processing results of the practical ground penetrating radar GPR data with these two migration methods.It is illustrated that migration can refocus the reflecting points in radar record to their true spatial location and provide the foundation for interpretation,thus improving precision of interpretation of(GPR)profiles.
