Implementation and Comparison of Imaging Methods for Ground Penetrating Radar

This work presents the comparison of the commonly used B-scan imaging method with a delay and sum (DAS) beam-forming algorithm for ground penetrating radar (GPR). Utilizing an implemented ultra-wideband (UWB) stepped frequency GPR, using only in-phase data, real-world measurements are compared and discussed. The reduced complexity of the proposed system could increase the speed of data acquisition and processing as well as reduce system cost while providing similar measurement accuracy. This could be of interest for applications such as the localization of underground utility piping, archaeology or mine detection.
