Experimental results from a stepped frequency GPR
In the framework of a nationally funded project, a 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 was
described in a previous paper (Alberti et al., 2002). As new aspects, the system is a stepped frequency GPR that
can work both in gated and ungated mode, and the antennas can be moved automatically in a controlled fashion.
As aspects of geophysical interest, the system is exploitable in situations wherein a high resolution and a shallow
penetration in the soil (a few meters) are required. Possibly, this is an example of probing a landscape. This paper
completes the results of Alberti et al. (2002), wherein laboratory tests where described, by providing the main
results obtained during an outdoor experimental campaign, performed fi rst in a controlled site and then in an
archaeological site

Current development status of MiniSAR, an Italian airborne interferometric SAR
MINISAR is a compact airborne interferometric SAR potentially suitable for many applications but mainly finalized for the production of technical topographic maps and monitoring the evolution of landslides events and assessing their extension and risk area. The program is co-funded by the Italian Ministry for Education, Universities and Research (M.I.U.R.). The hardware consists in an airborne X-band radar, able to obtain a resolution less than a meter (because of a 280 MHz stepped chirp signal) and an altimetric accuracy less than 7 meters. Such an accuracy derives from an equivalent 1.5 meters baseline and the high gain antennas that let MINISAR to use a transmitted power of only 80 W. The system will be mounted on board of a small platform and it is thought to have future development for unmanned platform. Data will be processed using a chirp scaling algorithm in order to obtain the two Single Look Complex (SLC) images which can be then processed to obtain high accuracy Digital Elevation Model (DEM)
A stepped frequency GPR system for underground prospectingGiovanni Galiero, Raffaele Persico, Marco Sacchettino and Sergio Vetrella
loped 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, they show that the system can guarantee a dynamic range of about 96 dB

Interferometric experiments with the first Italian airborne P-band radar
This work aims to describe the characteristics and the status of development, including the results of a first preliminary testing campaign, of a low frequency airborne imaging radar developed in Italy for the Italian Space Agency
The ASI P-Band Helicopter-Borne Integrated Sounder-Sar System: Preliminary Results of The 2018 Morocco Desert Campaign
The Italian Space Agency (ASI) has recently entrusted CO.RI.S.T.A. with the development of a radar system that can be mounted onboard small airplanes or helicopters and may operate, at different frequencies belonging to the P-Band, either as Synthetic Aperture Radar (SAR) or as Sounder. In this work, we present preliminary results of the helicopter-borne desert campaign carried out with this system in 2018 over the Erfoud area, Morocco, in the frame of a project that has involved different public Italian Research Institutes and Universities
