Comparison between diverse algorithms for GPR applications
A ground penetrating radar (GPR) system for detecting the location of buried objects has many civilian and military applications. A stepped frequency continuous wave (SFCW) ultrawide band (UWB) GPR is implemented with different signal processing algorithms. Three algorithms are compared in terms of complexity and accuracy in locating the position of buried objects under the sand. The algorithms are delay-sum beamforming, inverse Fourier transform and Green's function. We used two UWB antennas; AUP8-2P4 antenna, with operational frequency covering from 0.6 to 1.1 GHz, in addition to AU1-4P5 antenna with operational frequency covering from 3.6 to 4 GHz to compare their effect on the resolution based on experimented results for small and large metallic objects.
