Ground Penetrating Radar
We are currently purchasing our own GPR set to further the work on the Bronze Age, Roman/British settlement we discovered during our field survey we commissioned with Sussex Archaeology. The set will also be used on the hoard sites etc. to determine if there is underlying Archaeology. No digging below the plough line will be undertaken unless supervised by qualified Archaeologists
pulses are generated at a surface antenna and then propagated into the
ground. When they encounter buried discontinuities (for instance stones
surrounded by sand or changes in the composition of stratigraphic units),
a portion of the radar energy is reflected back to the surface and recorded
again at the antenna.
are moved along the ground surface in transects within a grid.
many transects are collected in a grid a three-dimensional data base
The depth of penetration, and the resolution of buried features is primarily controlled by the frequency of the antenna.
radar energy moves through the ground, any discontinuity will reflect
energy back to the surface.
GPR processing produces two-dimensional vertical profiles of each reflection
series of three-dimensional maps can be produced using what are called
this mapping method each time-slice becomes analogous to a map of all
materials in arbitrary excavation levels.
