A new reconfigurable stepped frequency GPR system, possibilities and issues; applications to two different Cultural Heritage Resources

Some results achieved from a reconfigurable stepped frequency GPR system will be presented. The aim is to show the possibilities of a reconfigurable architecture for a GPR system within the non-invasive prospecting of the Cultural Heritage. In particular, two sites (indoor and outdoor, respectively) have been chosen, in order to test the system in different situations that pose different problems. The same sites have been prospected also with a commercial pulsed system, in order i) to work out a comparative heuristic analysis and ii) to plan possible future advancements improving the reconfigurable system.
