Buried objects characterization via non-destructive imaging is of great interest in the modern scientific community because of the wide range of applications, spanning from civil engineering to archeological field and security. Common GPR approaches are based on the analysis of radagrams. Accordingly, they require strong human expertise and do not directly provide electromagnetic information about the target. LEMMA’s researchers have given many contributions in this field by proposing a tomographic approach to the topic. Accordingly, they developed suitable models to deepen peculiar features of subsurface imaging problem [1],[3], and tools to deal with realistic scenarios. Amongst these tools it is possible to found both qualitative [5],[7] and quantitative [2],[4],[6]-[9] imaging approaches. In particular, in [9] the possibility of adopting a contactless measurements configuration has been investigated against experimental data. Finally, the book chapter [6] summarizes the developed imaging techniques for subsurface inspection through the ‘virtual experiments’ framework.
