Ground Penetrating Radar (GPR) is a non-destructive geophysical method that transmits high-frequency radio-wave pulses into the ground and records reflections from materials with contrasting electrical properties. It supports the detection and depth estimation of archaeological remains, cavities, utilities, bedrock and stratigraphic boundaries, producing vertical radargrams, horizontal depth slices and three-dimensional subsurface models.
Ground Penetrating Radar (GPR) is a non-destructive electromagnetic geophysical method used to image subsurface structures. It transmits short, high-frequency radio-wave pulses into the ground and records energy reflected from boundaries between materials with contrasting electrical properties, particularly conductivity and dielectric permittivity. By measuring signal travel time and estimating wave velocity, the depth of buried reflectors can be determined. GPR is widely applied to identify archaeological remains, cavities, stratigraphic boundaries, bedrock, fractures, utilities and groundwater-related features. Survey data are collected along parallel profiles and displayed as vertical radargrams; closely spaced grids also enable horizontal depth slices and three-dimensional subsurface models. Multichannel GPR systems integrated with RTK-GNSS for accurate positioning can increase the spatial coverage and resolution. Penetration and resolution depend on antenna frequency and ground conditions, with conductive, clay-rich, saline or wet soils limiting performance.
