New method for GPRS cellular network traces exploitation
2010 17th International Conference on Telecommunications, 2010In 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

Complex impedance mapping using GPR survey methods
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004GPR surveys are normally processed to provide reflection images free of static offsets and long period drift. However in many surveys the raw data is observed to contain systematic decays consistent with Cole-Cole models of complex impedance. The resulting time-constants can be used to provide additional constraints for geotechnical investigations of ...

GPR Signal Denoising and Target Extraction With the CEEMD Method
IEEE Geoscience and Remote Sensing Letters, 2015In 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.

GPR Methods for Hydrogeological Studies
2005Use of ground-penetrating radar (GPR) for geologic applications grew considerably in the 1970s. In recent years, use of GPR has increased in hydrogeological investigations, since the presence or absence of water dominates GPR responses.

Evaluation of EMD-based Methods on GPR Data
Proceedings, 2014Empirical Mode Decomposition (EMD) is a relatively new technique for analysing non-linear and non-stationary time series. Ensemble Empirical Mode Decomposition (EEMD) and Complete Ensemble Empirical Mode Decomposition (CEEMD) are noise assisted and adaptive methods based on EMD.

Derivative seismic processing method for GPR data
IGARSS'97. 1997 IEEE International Geoscience and Remote Sensing Symposium Proceedings. Remote Sensing - A Scientific Vision for Sustainable Development, 2002Ground-penetrating radar (GPR) is a newly developed geophysics method. It belongs to one of the electromagnetic methods. In a broad sense, it is also a remote sensing technique, but the processing method for GPR data is quite different with the one for remote sensing data.

An Improved EMD Analysis Method for GPR Images
2011 International Conference on Computational and Information Sciences, 2011The EMD method can be adopted to analyze the GPR echo image because it is adaptive for non-stationary and non-linear signals. However, the direct wave in GPR signal contains considerable energy which will generate false object, even aggravate the end effect.

An Efficient Sampling Method for Cross-Borehole GPR Imaging
IEEE Geoscience and Remote Sensing Letters, 2018This letter reformulates the recently proposed qualitative imaging technique, which is the near-field orthogonality sampling method (NOSM), for 2-D cross-borehole ground penetrating radar (GPR) applications. The NOSM employs the reduced scattered electric field as its indicator function. To derive a relationship between the scattered electric field and
