Applying Ground-Penetrating Radar and Microwave Tomography Data Processing in Cultural Heritage State of the art and future trends

Ground penetrating radar (GPR) is a valuable diagnostic tool for cultural heritage (CH) monitoring and archaeological prospecting applications owing to its ability to inspect optically opaque media and provide information about hidden/buried targets. This article deals with a review of theoretical and practical aspects for an effective and reliable use of GPR in CH applications. Specifically, the focus is on data processing via a linearized microwave tomographic approach. In this context, theoretical and practical issues related to GPR imaging such as clutter and artefacts mitigation as well as three-dimensional reconstruction of large spatial domains are addressed. Finally, an applicative example concerning a survey performed at the Archaeological site of Pompeii, Italy, is presente
