A Highly Digital Multiantenna Ground-Penetrating Radar (GPR) System
IEEE Transactions on Instrumentation and Measurement, 2020Ground-penetrating radar (GPR) is a widely popular sensing method with broad applications in nondestructive subsurface imaging. This article presents a multistatic GPR for vehicle-mounted roadway and utility monitoring applications that employ several ...

Ground-penetrating radar is a near-surface geophysical method that reflects radar waves from buried interfaces in the ground and produces two and three-dimensional images of buried geological and anthropogenic units. When many thousands or hundreds of thousands of reflections are displayed in two-dimensional vertical slices, profiles of these units can

Ground-penetrating radar is a typical sensor system for analyzing underground facilities such as pipelines and rebars. The technique also can be used to detect an underground cavity, which is a potential sign of urban sinkholes.

Freshwater Ground-penetrating Radar
Near Surface 2009 - 15th EAGE European Meeting of Environmental and Engineering Geophysics, 2009The dielectric permittivity, conductivity and velocity of fresh water causes GPR to work well on and in this media. Various publications, conference abstracts and personal comments quote different antenna frequencies as optimal for freshwater surveying: these are tested with some simple field experiments. Few publications comment on antenna orientation

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

Fundamentals of Ground Penetrating Radar
Symposium on the Application of Geophysics to Engineering and Environmental Problems 1989, 1989Ground penetrating radar (GPR) is a relatively new technique for investigating shallow geologic, engineering and hydrologic features. The principles and theory are based on the wave equation derived from Maxwell’s Equations for electromagnetic wave propagation, and the antenna designs have evolved from field testing.

Ground penetrating radar tomography
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002Presents a survey of theory and practice in tomographic imaging of subsurface features utilizing ground penetrating radar (GPR). The discussion includes: (i) A brief review of the equations governing radar scattering culminating in the Lippmann Schwinger (LS) equation.
