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. %K stepped frequency radar %K GPR system %U http://www.annalsofgeophysics.eu/index.php/annals/article/view/4368
