From Maxwell equation and according to the transmitting feature of high-frequency radar wave inmedia,the wave equation of radar signal is deduced,by which the imaging formula for perturbation of velocity is obtained, and velocity singularity of interface is analyzed by wavelet operator.In this way the imaging of the underground interface can be completed easily. Calculations prove that this new technique is effective.
