Comparison of two differential GPR systems for imaging objects under a reflection configuration

This work deals with the problem of imaging perfectly conducting objects from ground penetrating radar surveys. The goal is to analyze and compare two differential antenna systems with receiving antennas horizontally and vertically displaced with respect to the transmitting antenna. To this end, synthetic radargrams are generated by a finite-difference time domain forward solver for both configurations. After, a microwave tomographic approach is adopted to process the scattered field differential data and facilitate the comparison among the systems.
