Ground-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...
متن کاملGround Penetrating Radar Fundamentals
Ground penetrating radar (commonly called GPR) is a high resolution electromagnetic technique that is designed primarily to investigate the shallow subsurface of the earth, building materials, and roads and bridges. GPR has been developed over the past thirty years for shallow, high resolution investigations of the subsurface. GPR is a time-depen dent geophysical technique that can provide a 3...
متن کاملStrong spatial variability of snow accumulation observed with helicopter-borne GPR on two adjacent Alpine glaciers
This study compares high-resolution helicopter-borne radar measurements to extensive groundbased profiling of the snow cover on Findeland Adler Glacier, Switzerland. The results demonstrate that derived accumulation values of either method are well in accordance. The spatial distribution of radar based snow depth allows a clear distinction of three zones of different accumulation characteristic...
متن کاملImproving Snow Water Equivalent Estimates with Ground Penetrating Radar by Measuring on Multiple Channels
Snow water equivalent (SWE) of a snowpack is often measured along well-chosen transects representative of an area of interest, such as a drainage basin, to capture spatial distribution of SWE, which is of great interest for many applications. For example, it is a useful input to the new generation of hydrological models used for snow melt run-off predictions. A time-effective method to perform ...
