Features: This book primarily introduces the basic principles, detection technologies, and related products of non-destructive detection of underground targets, with a focus on practical content. The book is divided into 8 chapters.
Chapter 1: Technical Physics Foundation of Underground Target Detection, including the dielectric properties of earth materials, general laws of electromagnetic wave reflection, transmission, and propagation, main technical parameters of underground target detection, and basic signal processing.
Chapter 2: Metal Detectors, mainly discussing the basic principles, circuit analysis, and key steps for making and using 6 typical metal detectors.
Chapter 3: Balanced Bridge Detectors, introducing the basic principles of balanced bridge sensors, the U.S. AN/PRS mine detectors series, the U.S. GDE mine detection system, and related products at home and abroad.
Chapter 4: Impulse Ground Penetrating Radar (GPR), mainly introducing time-domain signals, transient electromagnetic scattering characteristics, the principles and products of impulse GPR, and also introducing newly developed ultra-narrow impulse GPR systems in recent years.
Chapter 5: Harmonic and Combined-Wave GPR, covering nonlinear targets and their harmonic or combined-wave reradiation, nonlinear radar cross-section, nonlinear radar equations, and harmonic and combined-wave GPR products.
Chapter 6: FMCW GPR, mainly introducing the basic principles of FMCW, noise leakage and suppression in frequency-modulated continuous-wave GPR, and Israeli mine detection products.
Chapter 7: Step-Frequency GPR, including the phase-coherent detection principle of step-frequency methods and step-frequency GPR products.
Chapter 8: Tomographic Imaging Technology, introducing the principles of tomographic imaging, multi-frequency diffraction tomographic imaging technology, and experimental detection results of tomographic imaging.
This book can serve as a reference for university students, graduate students, and scientists and engineers. Some deeper content and newer technologies can also guide professional researchers in the development and research of new products.
