Nuove tecniche di prospezione archeologica mediante strumenti multifrequenza

Abstract

En
In this work we present some results obtained in a measurement survey performed with a stepped frequency Ground Penetrating Radar (GPR). The GPR and the survey at hand have been conceived for archaeological purposes.The stepped frequency GPR has been developed by the Italian Research Consortium CO.RI.S.T.A. in the framework of the ARCHEO project, founded by Italian M.U.R.S.T. The system can work within a large bandwidth and both in ungated and gated mode. It is equipped with a positioning system able to move the transmitting and receiving antennas of the GPR independently on each other and to place them automatically and in a precise fashion. The GPR has been tested first in laboratory of CO.RI.S.T.A., then in a controlled site, and finally in the real archaeological site of Cales, near Capua (Southern Italy), preventively and appositely studied by a team of archaeologists. The final results obtained in the field have been coherent with a previous prospecting performed at Cales and have individuated some new further buried targets, whose nature is still unknown at the moment.
