Abstract
There are many techniques to focus raw B‐scan ground penetrating radar (GPR) images mainly distorted from well‐known hyperbolic dispersion. In this study, we apply a hyperbolic summation (HS)‐type focusing technique to the simulated and measured GPR data at C‐band frequencies. The formulation of the proposed HS method is presented. Numerical GPR images for different metal targets are generated by the help of a physical optics simulation code. An experimental set‐up is constructed with the help of a stepped frequency radar system and corresponding B‐scan images are generated. Proposed HS method is applied to the measured B‐scan GPR data. Focused GPR images of different objects were obtained for both the simulated and the experimental data. © 2007 Wiley Periodicals, Inc.
