Ground Penetrating Radar (GPR) uses a high frequency radio signal that is transmitted into the ground and reflected signals are returned to the receiver and stored on digital media. The computer measures the time taken for a pulse to travel to and from the target which indicates its depth and location. We are the trading company specialty for used surveying equipment including robotic total station, gps gnss systems, 3d laser scanner, machine control, ground penetration radar, xrf analyzer, test and measurement equipment. 308 Balestier Road #16-18, Singapore, SG +65675567190; [email protected] Very dense ground penetrating radar (GPR) survey grids and three-dimensional data processing produce clear images of complex shallow-subsurface anatomy. Our field studies show submeter-resolution 3D images of human activity remnants, utilities, sedimentary structures, groundwater and fractures with millimeter aperture. 3D Ground Penetrating Radar for concrete inspection A patented survey kit, Aladdin enables the acquisition of 3D images with the highest resolution. Halving acquisition time, this GPR reveals shadowed and deep targets with its full-polar antenna.
