Abstract Estimation of position and shape of the object subsurface is one of the main problems in Ground Penetrating Radar(GPR) application. Migration method in domain of seismic techniques is effective to locate and reshape the object. The electromagnetic wave velocity parameter is the main factor influencing the precision of location. In this paper, the GPR images are handled with frequency-wavenumber migration on the base of applying minimum entropy method to estimate velocity parameter. Experimental results of simulation and GPR data prove its feasibility and validity.
