Monitoring Infiltration Process Seamlessly Using Array Ground Penetrating Radar

open access: yesAgricultural & Environmental Letters, 2016
Because an array ground penetrating radar (GPR) electrically switches any antenna combinations sequentially in milliseconds, both common-offset gather (COG) and multi-offset gather (MOG) data can be acquired almost seamlessly.

Investigating the internal structure of four Azorean Sphagnum bogs using ground-penetrating radar [PDF]

open access: yesMires and Peat, 2017
This study evaluates the applicability of ground penetrating radar (GPR) as a technique for determining the thickness and internal structure of four peat deposits on Terceira Island (Azores archipelago, mid-Atlantic region). The peatlands studied are all

Recursive Enhancement of Weak Subsurface Boundaries and Its Application to SHARAD Data

open access: yesRemote Sensing, 2022
Sedimentary layers are composed of alternately deposited compositions in different periods, reflecting the geological evolution history of a planet. Orbital radar can detect sedimentary layers, but the radargram is contaminated by varying background ...

Evaluation of Road Pavement and Subsurface Defects Mapping Using Ground Penetrating Radar (GPR) [PDF]

open access: yesEngineering and Technology Journal, 2014
GPR is frequently used for inspection road pavement (thickness estimation, damage detection and diagnosis), so this technique was selected for this purpose. Three types of antennas were used: 250, 500 and 800 MHz.

Review article: Feature tracing in radio-echo sounding products of terrestrial ice sheets and planetary bodies [PDF]

open access: yesThe Cryosphere
This paper aims to inform researchers and practitioners in radioglaciology about current and future trends in mapping the englacial stratigraphy of ice sheets. Radio-echo sounding (RES) is a useful technique for measuring the subsurface properties of ice

Hyperbola Occurrence in GPR Radargrams of Cracked Road Pavements: A Numerical Comparison of Top-Down and Bottom-Up Cracking

open access: yesInfrastructures
Ground-penetrating radar is widely used in non-destructive pavement evaluation, but the occurrence of multiple hyperbolic signatures in radargrams of cracked pavements remains insufficiently characterized, particularly for top-down and bottom-up cracking.
