Noggin Plus-Smart Cart system by Sensors & Software is used with a 250MHz or 500MHz antennas.
The tool provides information about the vertical distribution of the resistivity reflectors within the ground (stratigraphic information that can be also used for 3D reconstructions of the subsurface). G.P.R. can be used in a series of applications like the mapping of the bedrock depth, the determination of the stratum thickness and the aquifer depth, the location of physical and artificial cavities in the subsurface, cracks in the bedrock and the tracing of the changes in the rocks composition. The method is specially used in Archaeometry for the detection of buried antiquities (walls, architecture, tombs, graves, etc).
