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.

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, with 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). With its lucid, comprehensive investigation of this revolutionary and cost-effective solution, Ground Penetrating Radar: Theory and Practice, Second Edition successfully bridges a gap between theoretical understanding and practical mastery, becoming the go-to reference title for a multitude of technical users with varied levels of expertise and across different applied disciplines.
