Analysis of high resolution GPR time-slices from archaeological sites in Italy

Recent developments in 3-D high-resolution multi-image processing and contouring, as opposite to destructive testing, have greatly contributed to improve the quality of geophysical information in archaeological reconnaissance surveying. Nowadays non-destructive ground-surface geophysical prospecting methods, which involve detailed physical and geometrical reconstruction of hidden ambient, are increasingly used for the investigation of archaeological sites. Ground Penetrating Radar (GPR) offers very high resolution sounding capability with detection of features of the order of a few tens of millimetres thickness at ranges of several metres. In this work, the results of two high-resolution GPR surveys carried out in order to detect superficial walls and floors, in two archaeological sites in Italy, characterised by different geological environmental conditions, are presented.
