Abstract:

This manuscript is the second part of a Ph.D. thesis previously published with the ISBN:978-88-98161-29-4. In the first part, the theoretical approach and the foundations of the reconfiguration of GPR systems have been exposed. Here, some measurement campaigns will be reported. In addition to the novel reconfigurable prototype stepped frequency GPR system (GPR-R), mentioned and detailed in the first part, a commercial pulsed GPR system and a commercial stepped frequency 3d-Radar GPR device were used aiming at performing a comparative analysis of the results of the different GPR equipments on some historical monuments and archaeological sites. This was done both in indoor and in outdoor conditions because the GPR performance is influenced by several environmental aspects. In particular, outdoor tests can be affected by changes in the weather, roughness of the surface and presence of grass, while indoor tests can be influenced by the most probable presence of fixed architectural obstacles. The GPR prospection have been performed in Puglia (Italy) in historical Churches (such as the former hospital of the Holy Spirit, in Lecce and the Church of St. John Baptist in Parabita, Lecce province) and in two important Archeological Parks (Egnazia (Brindisi) and Manduria (Taranto). Moreover, thanks to a support by the European Cost Action 1208, a collaboration with the 3d-Radar Company was also possible and made possible has a geophysical survey conducted in the main square of Trondheim (Norway).
