Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field *Up-to-date information and references *Effective handbook and primary research reference for both experienced practitioners and newcomers

This book, based on Transport and Urban Development COST Action TU1208, presents the most advanced applications of ground penetrating radar (GPR) in a civil engineering context, with documentation of instrumentation, methods and results. It explains clearly how GPR can be employed for the surveying of critical transport infrastructure, such as roads, pavements, bridges and tunnels and for the sensing and mapping of underground utilities and voids. Detailed attention is also devoted to use of GPR in the inspection of geological structures and of construction materials and structures, including reinforced concrete, steel reinforcing bars and pre/post-tensioned stressing ducts. Advanced methods for solution of electromagnetic scattering problems and new data processing techniques are also presented. Readers will come to appreciate that GPR is a safe, advanced, non destructive and noninvasive imaging technique that can be effectively used for the inspection of composite structures and the performance of diagnostics relevant to the entire life cycle of civil engineering works.

Ground Penetrating Radar: Theory and Practice is a practical guide to using this powerful underground surveying technique. The author uses her wide experience to explain the critical factors in using GPR and how parameters, such as wavelength, attenuation and loss need to be properly considered to obtain good survey results. The first chapter introduces the underlying physics and explains the formation of signal patterning. The next two chapters explain the significance of wavelengths for target detection, probing depths and resolution, and demonstrating the variety of signal presentation. Chapter four discusses why survey results are affected by water and air in the soil, and how this may affect depth readings. Additional chapters discuss a variety of methods for velocity calibration and suggests where they may be useful, challenging soil conditions and potential problem environments, data processing and a suite of useful techniques, amongst other important topics. The book gives a clear and formative guidance on understanding the critical factors in using GPR, as well as a checklist of surveying considerations. Covers the critical, practical factors in using a ground penetrating radar, including troubleshooting appropriate equipment selection Explains why wavelengths matter, providing practice calculations Offers insight into how to spot ringing (echo effects) and air signals, and how to distinguish these from subsurface data Enables the reader to understand the importance of calibration of transmission velocity and a range of methodsa

GPR Remote Sensing in Archaeology provides a complete description of the processes needed to take raw GPR data all the way to the construction of subsurface images. The book provides an introduction to the “theory” of GPR by using a simulator that shows how radar profiles across simple model structures look and provides many examples so that the complexity of radar signatures can be understood. It continues with a review of the necessary radargram signal processes needed along with examples. The most comprehensive methodology to construct subsurface images from either coarsely spaced data using interpolation or from dense data from multi-channel equipment and 3D volume generation is presented, advanced imaging solutions such as overlay analysis are introduced, and numerous worldwide site case histories are shown. The authors present their studies in a way that most technical and non-technical users of the equipment will find essentials for implementing in their own subsurface investigations.

Abstract Ground Penetrating Radar (GPR) Data Analysis deals with the problem of shallow subsurface imaging, which is motivated by the daily work of engineers, \eg those of municipalities.The concrete problem tackled in this thesis is motivated by the fact, that, at least in Germany, municipalities have knowledge about the existence of supply lines such as gas and water pipelines to cross and follow urban streets, while their actual position is often uncertain.The consequences are obvious:once a street undergoes maintenance works, pipes are easily broken.This also causes heavy problems to residents who are cut off from some supplies for a period of time. This thesis approaches a solution to the object detection problem in GPR data by means of (semi-)automated data analysis techniques, using Machine Learning methods.The problem is treated as a specialized problem for object detection in image data.In this application context, it is possible to integrate certain background knowledge and processing techniques in well-known Machine Learning methods. The thesis formalizes the problem first.A technical framework for the analysis of Complex Engineering Raw Data – CERD -, as a generalization of our current data at hand, will be used for all analysis methods developed.From a thorough data analysis, it becomes clear that our data labels are unsuitable for directly applying supervised Machine Learning methods.Therefore, we will be obtaining suitable ground truth data by semi-manually labeling more than 700 images by hand.The second part of the thesis presents both, supervised and unsupervised Machine Learning techniques for the detection of buried object locations.Techniques are introduced within the general context of object detection techniques within image data.The integration of geometrical background knowledge is shown to be feasible in all methods developed. This thesis will contribute in the followings: *The methodology and suitability of high-quality ground truth data for GPR data analysis is presented. *A conceptual framework along with its technical framework for the analysis of CERD is presented. *Intuitive, state of the art analysis methods for the interpretation of GPR data are presented, discussed, and evaluated. Zusammenfassung Die Bodenradaranalyse (Ground Penetrating Radar – GPR) bezeichnet ein Forschungsfeld, welches nicht-destruktive Radartechnologie einsetzt, um unterirdische Strukturen sichtbar zu machen.Diese Arbeit beschäftigt sich mit dem Teilbereich der unterirdischen Leitungsortung unter Zuhilfenahme überwachter maschineller Lernverfahren (Machine Learning Methoden).Halb-automatische Lernverfahren werden eingesetzt, da es sich um sehr große Datenmengen handelt, die derzeit noch vorwiegend händisch von Ingenieuren analysiert werden.Dieses stellt wesentliche Zeit-, Kosten- und Fehlerfaktoren dar, welche es zu optimieren gilt.Eine manuelle Bestimmung auf Basis bestehender Versorgungsleitungspläne ist besonders in Deutschland nicht möglich, da diese auf teilweise mehrere Meter ungenau und unter Umständen sogar unvollständig sind. Diese Doktorarbeit versucht, die Analyse von Bodenradardaten mit Hilfe überwachter Lernverfahren des `Machine Learnings’ zu automatisieren.Das allgemeine Vorgehen orientiert sich dabei an bekannten Bildverarbeitungsmethoden.Domänenspezifische Eigenschaften werden als Hintergrundwissen in die angewandten Verfahren integriert. Diese Arbeit besteht im wesentlichen aus zwei Teilen.Der erste Teil, bestehend aus den Kapiteln eins bis vier, führt die Problemstellung ein (Kapitel eins) und formalisiert diese (Kapitel zwei).Kapitel drei definiert den technischen Rahmen.Die vorliegenden Daten werden in Kapitel vier analysiert und vorverarbeitet.Aufgrund anwendungsspezifischer Besonderheiten wird in Kapitel fünf eine Methode dargestellt und eingesetzt, um qualitativ hochwertige Annotationen zu gewinnen, die die Grundlage für zu entwickelnde Analyseverfahren darstellt.Der zweite Teil präsentiert und analysiert die Qualität von unüberwachten (Kapitel sieben) und überwachten (Kapitel sechs, acht, neun) Lernverfahren.Hintergrundwissen wird, wann immer möglich, für eine Qualitätsverbesserung integriert. Die wesentlichen Inhalte dieser Arbeit sind folgende: *Hochwertige Annotationen für komplexe Sensordaten werden erhoben und aus verschiedenen Perspektiven verglichen und analysiert. *Ein konzeptuelles Framework für die Analyse komplexer Sensordaten wird präsentiert und prototypisch implementiert. *Intuitive Verfahren für die Bodenradar-Datenanalyse werden entwickelt, angepasst, vorgestellt und qualitativ verglichen.

There has long been a strong collaboration between geologists and archaeologists, and the sub-field of geoarchaeology is well developed as a discipline in its own right. This book now bridges the gap between those fields and the geophysical technique of ground-penetrating radar (GPR), which allows for three-dimensional analysis of the ground to visualize both geological and archaeological materials. This method has the ability to produce images of the ground that display complex packages of materials, and allows researchers to integrate sedimentary units, soils and associated archaeological features in ways not possible using standard excavation techniques. The ability of GPR to visualize all these buried units can help archaeologists place ancient people within the landscapes and environments of their time, and understand their burial and preservation phenomena in three-dimensions. Readership: Advanced students in archaeology and geoarchaeology, as well as practicing archaeologists with an interest in GPS techniques.
