This work deals with the retrieval of the dielectric characteristics of unknown objects buried in a lossy soil. The reconstruction performances of two deterministic inverse scattering (IS) techniques are assessed on real ground penetrating radar (GPR) data collected in an archaeological site in Cavallino (LE, Italy). Both approaches exploit a multi-resolution (MR) strategy to keep low the ratio between problem unknowns and non-redundant data. Moreover, they are respectively based on a multi-frequency (MF) and frequency-hopping (FH) approach for enabling the processing of wideband measurements. An illustrative experimental result is shown to verify the effectiveness and the potentialities of the two GPR-IS methodologies for archaeological investigations.

Abstract
This work deals with the retrieval of the dielectric characteristics of unknown objects buried in a lossy soil. The reconstruction performances of two deterministic inverse scattering (IS) techniques are assessed on real ground penetrating radar (GPR) data collected in an archaeological site in Cavallino (LE, Italy). Both approaches exploit a multi-resolution (MR) strategy to keep low the ratio between problem unknowns and non-redundant data. Moreover, they are respectively based on a multi-frequency (MF) and frequency-hopping (FH) approach for enabling the processing of wideband measurements. An illustrative experimental result is shown to verify the effectiveness and the potentialities of the two GPR-IS methodologies for archaeological investigations.File | Dimensione | Formato | |
