The Cathedral of St John in Valetta, Malta, represents a unique monument of historical importance. In this paper, we present the results of a detailed ground penetrating radar campaign performed in this Cathedral. The campaign was aimed at investigating the distribution of buried tombs under the mosaic floor of the main nave and of the lateral chapels of the Co‐Cathedral. The floor of the church shows a continuity of grave inscriptions in the main nave as well as in all lateral chapels. It was suspected, based on available historical documents, that only a part of the present‐day inscriptions corresponds to the original sepultures or tombs. The ground penetrating radar results presented here further highlight this conjecture and offer additional information regarding this important monument.

“…The data in Figure 2 have been processed with the Reflexw commercial code [14] according to a sequence processing composed by zero timing, background removal, gain vs. depth, one dimensional filtering, and Kirchoff migration. The propagation velocity has been evaluated equal to 0.08 m/ns according not only to the diffraction hyperbolas [15] but also according to a sequential migration [16] based on heuristic trials and visualizations of the relative results [17]. From the data, a two-layer structure of the soil is evident, and we have reasons to suspect also some horizontal variation of the characteristics of the soil.…”

In this contribution, some possible effects of large band electromagnetic interferences on Ground Penetrating Radar (GPR) data are shown, and a possible way to counteract them is shown, too. The mitigation of the interferences is implemented thanks to a prototypal reconfigurable stepped frequency GPR system, that allows to program the integration time of the harmonic tones vs. the frequency. In particular, an algorithm for the measurement of the effects of the interferences in the field (linked to the signal to interference ratio) is proposed and tested vs. experimental data. The paper will show some advantages and some drawbacks of the proposed procedure.
