2D Wavelet Decomposition and F-K Migration for Identifying Fractured Rock Areas Using Ground Penetrating Radar
نویسندگان
چکیده
The quality of the surrounding rock is crucial to stability underground caverns, thereby requiring an effective monitoring technology. Ground-penetrating radar (GPR) can reconstruct subterranean profile by electromagnetic waves, but two significant issues, called clutter and hyperbola tails, affect signal quality. We propose approach identify fractured rocks using 2D Wavelet transform (WT) F-K migration. migration handle Fourier analysis. WT mitigate clutter, distinguish discontinuity, provide signals with a good time-frequency resolution for In simulation, result from horizontal detail coefficients highlight crack locations reduce scattering signals. Noise has been separated WT. Hyperbola tails are decomposed vertical diagonal coefficients. Similar promising results have achieved in field measurement. Therefore, proposed process GPR identifying areas.

Ground Penetrating Radar Migration with Uncertain Parameters
In this paper the focusing principle of Kirchoff migration is described. This allows the introduction of optical focusing techniques that can be used to focus migration. Three focus measures are described that are useful for optimising migration. Simple optimisation routines are implemented that model uncertainties in the migration parameters. The focus measures are then used as cost functions ...

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 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...
