Analysis of a 2D microwave tomography algorithm applied to a differential configuration in GPR prospecting
This contribution aims at assessing the imaging capabilities of a differential configuration for GPR prospecting. In particular, two receiving antennas are piled on each other at the same abscissa, and the transmitting antenna is at a fixed horizontal offset and at the intermediate height between the two receivers. The analysis is carried out with the aid of a microwave tomographic algorithm based on the Born approximation. The considered GPR configuration allows to reject the direct coupling between the antennas in air, but worsens the filtering properties of the relevant scattering operator.
