Abstract:

This manuscript will contribute to a a broader research project handled in collaboration between the University of Bari, Italy, and IBAM-CNR. It focuses on the study of one of the geophysical methods most widely used: the Ground Penetrating Radar (GPR). Starting from an introduction to the methodology and to its technical aspects, a comparative analysis of two traditional GPR systems has been reported elsewhere. In particular, some benefits and limitations have been analyzed from a theoretical and a practical point of view of a pulsed as well as a stepped frequency system. At the same time, a novel reconfigurable prototype stepped frequency GPR system (GPR-R), implemented in 2012, has been presented and examined. The basic idea behind the reconfigurability approach in the GPR context consists to have a system in which it is possible to modify some parameter according to the investigated scenario. These possibilities maximize some performances of the system and allow an a-posteriori optimization of the data. The reconfigurable parameters of the new equipment refer to the time integration of each harmonic signal, to the antennas and to the radiated power. Each parameter have been detailed and some laboratories tests have been also illustrated.
