Intra-wall diagnostics via a microwave tomographic approach

The problem of diagnosing the internal status of a masonry structure by means of a non-destructive electromagnetic technique, based on a microwave tomographic imaging algorithm, is dealt with. The study is first developed through numerical arguments under a two-dimensional scalar geometry. Then, the microwave imaging algorithm is checked against experimental data collected in situ at the Carmine’s church belfry in Naples, Italy, by means of a ground penetrating radar system. The features of two different methods for clutter removal are also discussed.
