GPR Signal Denoising and Target Extraction With the CEEMD Method

IEEE Geoscience and Remote Sensing Letters, 2015
In this letter, we apply a time and frequency analysis method based on the complete ensemble empirical mode decomposition (CEEMD) method in ground-penetrating radar (GPR) signal processing. It decomposes the GPR signal into a sum of oscillatory components, with guaranteed positive and smoothly varying instantaneous frequencies.

The GPR refraction method

Geophysics, 2002
Abstract Refracted phases have been a recognized feature in wide-angle common midpoint (CMP) and common shotpoint (CSP) ground-penetrating radar (GPR) surveys for many years, but historically their use has been limited and overshadowed by conventional reflection profiling techniques.

An image reconstruction method using GPR data

IEEE Transactions on Geoscience and Remote Sensing, 1999
The spatial resolution of a ground penetrating radar (GPR) system using traditional interpretation methods is largely dependent on the isolations of echoes. It is difficult to identify weak echoes that are mixed with either direct waves or other larger echoes; especially, when the media is absorptive, the reflections cannot be identified from the tail ...

Detection of Buried Objects by the GPR Method

Fifth International Conferention on Ground Penetrating Radar, 1994
The ground penetration radar (GPR) technique is compared with two seismic methods, the spectral-analysis-of-surface-waves (SASW) and the crosshole, for detection of buried objects. Tests were performed in a 7 m diameter by 2 m deep sand bin in the G. G. Brown Lab of the University of Michigan.

New method for GPRS cellular network traces exploitation

2010 17th International Conference on Telecommunications, 2010
In the idea to create a realistic model of mobility and traffic for the networks of 3rd and 4th generation, we have studied many techniques of modeling and planning. Our choice was for the real network traces exploitation techniques, mainly because compared to other techniques this technique is very adapted to the real modeling. Although this technique
