Abstract
In the classical B-Scan ground penetrating radar (GPR), the collected data represented in the image domain, depict undesired hyperbolic effects and have low resolution features. In this work, we present frequency-wavenumber based Synthetic Aperture Radar (SAR) focusing technique to solve this problem. The formulation of algorithm is given and applied to both the simulation data obtained by a physical optics shooting and bouncing ray (PO-SBR) code and to the measured GPR data from real soil environment. Simulation and the measurement results demonstrate that proposed algorithm is very effective in achieving well-focused GPR images with high lateral resolutions.
