Abstract

In the framework of ARCHEO, a national research project funded by the Italian Ministry for Universities and Scientific and Technological Research (MURST), a new Ground Penetrating Radar (GPR) has been developed by the Italian Consortium for Research on Advanced Remote Sensing Systems (CO.RI.S.T.A.). The system has been specially designed to satisfy archaeological requirements and it will be used to identify and characterise buried objects. The system is a stepped frequency GPR. It can work within a wide band of frequencies both in gated and ungated mode, and it has been already widely described in Alberti et al. (2000). This paper describes the results of calibration tests in ungated mode performed in the CO.RI.S.T.A. laboratory. In particular, it is shown that the system can guarantee a dynamic range of about 96 dB.

SFGPR RFI Suppression Using Wavelet Packet Selective Algorithm

“…As a result, radio frequency interference (RFI) appears in the received signal [1]. RFI affects the normal operation of the system, especially working around cities and towns [2][3]. Currently, RFI suppression is already becoming one of the key technologies which are studied in GPR.…”
