An overview of ground-penetrating radar signal processing techniques for road inspections

Abstract

Ground-penetrating radar (GPR) was firstly used in traffic infrastructure surveys during the first half of the Seventies for testing in tunnel applications. From that time onwards, such non-destructive testing (NDT) technique has found exactly in the field of road engineering one of the application areas of major interest for its capability in performing accurate continuous profiles of pavement layers and detecting major causes of structural failure at traffic speed. This work provides an overview on the main signal processing techniques employed in road engineering, and theoretical insights and instructions on the proper use of the processing in relation to the quality of the data acquired and the purposes of the surveys

Characterization of complex groundwater flows in the environment of singular buildings by combining hydrogeological and non‐destructive geophysical (ground‐penetrating radar) techniques: Punta Begoña Galleries (Getxo, Spain)

“…This correlation was used for time–depth conversion of the acquired radar datasets. The respective average velocities in the interpretations relative to the depths (ground truthing method) (Benedetto, Tosti, Bianchini Ciampoli, & D'Amico, ; Conyers & Lucius, ) were calculated using Equation . These velocity estimates for each dataset should be considered as acceptable given the inherent imprecision of the GPR technique (Conyers, ; Conyers & Lucius, ).…”

“…Post‐acquisition processing procedures were necessary for application to the raw field GPR datasets (Benedetto et al, ; Conyers, ). In this study, a data processing procedure was applied to the raw radar datasets using RADAN software developed by Geophysical Survey Systems, Inc. (GSSI).…”

Advanced Ground Penetrating Radar Signal Processing Techniques

“…Benedetto et al in [1] provide a review article on the main signal processing techniques employed in road engineering using GPR. Starting with the theoretical basis of GPR, they provide the main GPR data processing techniques utilized in road monitoring they present a number of significant and relevant GPR applications.…”

Research on GPR image recognition based on deep learning

“…Ground penetrating radar (GPR) enables efficient and non-destructive detection of underground targets based on the reflection and scattering of electromagnetic waves in different media [1]. GPR has been widely used in geological survey, tunnel structure layer inspection, archeology, glacier exploration and other fields [2,4]. There are differences in the relative permittivity and conductivity of different dielectric materials, and various dielectric structures will show different waveform characteristics on GPR images [5].…”
