Ground-penetrating radar is a technology that uses pulses of electromagnetic radiation to penetrate the surface of the ground, and go below to reveal any anomalies in soil or other materials. Ground-penetrating radar uses microwave band frequencies, generally from 10 MHz to 1 GHz. Advertisements ...
What is ground penetrating radar? - Ground penetrating radar GPR is a non-destructive geophysical survey method that can detect subsurface features without drilling, probing, or digging. GeoModel, Inc. conducts ground penetrating radar GPR surveys nati
Ground Penetrating Radar (GPR) technology is commonly used in noninvasive evaluations to detect subsurface objects, to assessroad pavements, to assessrebar corrosionin bridges, and to evaluate structural faults. This technique is capable of providing planimetric position (x, y) and depth (z) of ...
