Strategy of GPR Searching for Low Radar Contrast Plastic Pipes in Ground

摘要

The results of computer simulation of pulse signal scattering by a plastic pipe buried in the ground as well as simulation results of ground penetrating radar (GPR) image of ground-filled trenches have been represented in the work. The "skeleton diagram" of a trench image has been developed. The strategy of GPR searching for low radar contrast plastic pipes in ground (in back-filled trenches) has been considered on the basis of indirect criterion which is the existence of a trench containing buried pipes
