Ground penetrating radar for tunnel detection
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Ground penetrating radar (GPR) systems have important civil and military applications and can be used for surveying subsurface structures such as bunkers, tunnels and buried pipes. However, GPR systems for detecting deep tunnels still face many challenges, and their performance often depends on soil types, specific targets and subsurface geological ...

UWB LNAs for ground penetrating radar
2009 IEEE International Symposium on Circuits and Systems, 2009Two LNA topologies for use in UWB systems are examined and compared in this paper. Design specifications have been derived from a ground penetrating radar system which is the target application. Circuits have been designed to cover the frequency range from 3.1GHz to 10.6 GHz.

Ground Penetrating Radar (GPR) called also Radar (Radio Detecting and Ranging) is an application of electromagnetic (EM) waves. It has been developed in the last decades for detection, distance measurement, defects and anomaly localization, and characterization of dielectric materials such as soil, concrete, masonry and wood. The frequency range of the

Theory of ground-penetrating radars
Journal of Inverse and Ill-Posed Problems, 1997Summary: An inverse problem is formulated and its analytical solution is given. The problem consists in determining the conductivity and permittivity of the inner Earth layers from the measurements of electromagnetic fields on the surface of the Earth. The problem is of interest, for example, in geophysics.

Selected Bibliography on Ground Penetrating Radar
Symposium on the Application of Geophysics to Engineering and Environmental Problems 1988, 1988The following is a selected bibliography on ground penetrating radar. It is excerpted from a more comprehensive bibliography (approximately four times larger) to be published next year in the second volume of the Society of Exploration Geophysicist's Electromagnetic Volumes, edited by Misac Nabighian.

Efficient Deconvolution of Ground-Penetrating Radar Data
IEEE Transactions on Geoscience and Remote Sensing, 2015The time (vertical) resolution enhancement of ground-penetrating radar (GPR) data by deconvolution is a long-standing problem due to the mixed-phase characteristics of the source wavelet. Several approaches have been proposed, which take the mixed-phase nature of the GPR source wavelet into account.

The ground penetrating radar system
2021Radar is an acronym for RAdio Detection And Ranging. Its operating principle is analogous to the broader pulse-echo (or pitch-catch) technique, except that pulsed electromagnetic (EM) waves (short radio waves or microwaves) are used instead of stress waves.

Introduction to ground penetrating radar
2021This chapter has briefly discussed the use of GPR as an NDT and an NDE tool. In contrast to other NDT methods, GPR is based on EM wave propagation, which provides advantages and limitations. Among the advantages, one can cite relatively low-cost of survey, compact size of equipment, excellent trade-off between resolution and depth of detection, and ...

Magnetic Antennas for Ground Penetrating Radar
The concept for a novel new antenna design is presented and investigated for application to ground penetrating radar (GPR). The proposed new antenna design is called the shielded magnetic bowtie antenna (MBA). As the name suggests, it is predominately constructed from a bowtie-shaped volume of magnetic material that is fed from the centre of the ...openaire +2 more sources
