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 کاملCompressive sensing for subsurface imaging using ground penetrating radar
The theory of compressive sensing (CS) enables the reconstruction of sparse signals from a small set of non-adaptive linear measurements by solving a convex ‘1 minimization problem. This paper presents a novel data acquisition system for wideband synthetic aperture imaging based on CS by exploiting sparseness of pointlike targets in the image space. Instead of measuring sensor returns by sampli...
متن کاملAn Interferometric Technique for Synthetic Aperture Ground-Penetrating Radar
-Many synthetic aperture radar (SAR) algorithms for ground-penetrating radar involve making measurements along a single path and using the collected data to form a twodimensional image of the scattering object. In the calculation of these images, certain assumptions are made about the scattering objects; mainly, that the reflections are occurring directly below the antenna location, which is no...
