This work aims at presenting the main results achieved by Working Group (WG) 1 “Novel Ground Penetrating
Radar instrumentation” of the COST (European COoperation in Science and Technology) Action TU1208 “Civil
Engineering Applications of Ground Penetrating Radar” (www.cost.eu, www.GPRadar.eu).
The principal goal of the Action, which started in April 2013 and is ending in October 2017, is to ex-

This paper deals with a geophysical experimental activity carried out in the Maxentius Complex, an archaeological site located in Rome, Italy. The objective of this study was to evaluate the feasibility of GPR for the structural detailing of buried roman baths structures. As a result, GPR allowed to confirm the literature-based information, i.e. to precisely locate the tanks of the thermal area. Their presence was already known through previous excavation then buried and no more visible.

This paper investigates the performance of an advanced imaging procedure for ground penetrating radar (GPR) operating in contactless configuration, i.e., when data are collected at variable distances from the air-soil interface. A data processing procedure is presented, based on an advanced implementation of a microwave tomographic approach. This improved version, recently proposed by the authors, is able of accounting for the near-field distribution generated by a directional transmitting antenna.

In the last years, Ground Penetrating Radar (GPR) technology has been extensively used in several different fields, including archaeology and cultural-heritage diagnostics. The integration of GPR with other positioning devices, such as a Global Positioning System (GPS) and an Inertial Measurement Unit (IMU), can significantly improve the accuracy of buried-object location, by means of an efficient control of GPR route and attitude.

In Europe, the attention to efficiency and safety of international railway freight transport has grown in recent years and this has drawn attention to the importance of verifying the clearance between vehicle and lining, mostly when different and variable rolling stock types are expected. This work consists of defining an innovative methodology, with the objective of surveying the tunnel structures, verifying the clearance conditions, and designing a retrofitting work if necessary.
