Ground Penetrating Radar: Theory and Practice, Second Edition provides well-thought-out, fully updated, and expanded coverage of this NDT, trenchless technique for investigating the subsurface. Written by a recognized field specialist, the volume clearly explains not only how the technology works with introductions to the underlying physics and formation of signal patterning, but also spotlights how it can be successfully applied, including experiential insights into how parameters such as wavelength, attenuation (loss), environment, target size, and depth need proper consideration in any sampling strategy to obtain good survey results.Additional chapters explore a variety of methods for velocity calibration and suggest where they may be useful, review data processing, and address signal loss in challenging soil conditions and potential problem environments with a suite of useful resolution best practices. New to this edition are discussions on specialist GPR applications and state-of-the-art innovations (e.g., data digitization tools; machine learning, deep learning, artificial intelligence to improve detection and reliability in data interpretation; and robotization).Covers critical, practical factors in using ground penetrating radar, including troubleshooting appropriate equipment selectionExplains why wavelengths matter through built-in practice calculationsOffers insights into how to spot ringing (echo effects) and air signals, and how to distinguish them from subsurface dataHighlights the importance of understanding the basic physics involved in using a GPR and calibration of transmission velocity by a range of methodsBuilds on known problems to steer the practitioner towards more viable survey procedures
