Cultural Heritage Monitoring via GPR Enhanced by Microwave Tomography

Ground Penetrating Radar (GPR) is a popular non-invasive diagnostic device suited for cultural heritage (CH) monitoring applications thanks to its capability to detect targets located in visually opaque media. In this contribution, we provide a brief overview on the main technical aspects to assure a reliable use of GPR technology within CH monitoring and archeological prospections. The main emphasis is given to the data processing, and in particular to the microwave tomography approach. A case study regarding the 3D subsurface mapping of a crypt flooring in the Sant'Agnese church of Roma, Italy, is reported for demonstration purposes.
