Efficient Large-scale Underground Utility Mapping Using a New Multi-channel Ground-penetrating Imaging Radar System
Ground-penetrating imaging radar (“GPiR”) is a new technology that combines standard GPR (Ground-Penetrating Radar) with accurate positioning and advanced signal processing to create three dimensional (3D) images of the shallow subsurface. These images can reveal soil conditions and buried infrastructure—such as utility lines and conduits—down to depths of about 2 to 3 m (in typical organic so...
متن کاملA Multi-Scale Weighted Back Projection Imaging Technique for Ground Penetrating Radar Applications
In this paper, we propose a new ground penetrating radar (GPR) imaging technique based on multi-scale weighted back projection (BP) processing. Firstly, the whole imaging region is discretized by large scale and low-resolution imaging result is obtained by using traditional BP imaging technique. Secondly, the potential targets regions (PTR) are delineated from low-resolution imaging result by u...
متن کاملSubsurface Imaging using Ground-Penetrating Radar Measurements
Much work has been done toward reconstructing the electrical parameters of an unknown buried object. Many methods, and accompanying results from simulations, have been presented. Most research in the area, however, has been in developing imaging algorithms that have been tested primarily through computer simulation. This paper presents a newly constructed facility for ground-penetrating radar e...
متن کاملGround-Penetrating Radar
Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method that can quickly and accurately locate buried archaeological features, artifacts, and important cultural strata in the near-surface. The GPR method has been especially effective in certain sediments and soils between about 20 cm and 5 m below the ground surface, where the targets to ...
متن کاملGround - Penetrating Radar ( Paper
GPR senses electrical inhomogeneities, with these manifested, for example, by the electrical contrast of a metal mine in the presence of a far-less-conducting soil background. Of much more difficulty, GPR senses the electrical inhomogeneity caused by a dielectric (plastic) landmine in the presence of soil. Often this contrast is very weak, implying that the landmine GPR signal is very small. Th...
