Ground Penetrating Radar (GPR) is a powerful sensing technology widely used for the non-destructive assessment of a variety of structures with different properties including dimensions, electrical properties, and moisture. After an introduction to the underlying concepts, this book guides the reader through the development and use of a GPR system, with an emphasis on the parameters that can be optimized, the theory behind assessment, and a coherent methodology to obtain results from a measured or simulated GPR signal. The authors then embark on a detailed discussion of support tools and numerical modelling techniques that can be applied to improve readings from GPR systems. Ground Penetrating Radar is of interest to engineers, scientists, researchers and professionals working in the fields of ground penetrating radar, non-destructive testing, geoscience and remote sensing, antennas and propagation, microwaves, electromagnetics and imaging. It will also be of use to professionals and academics in the fields of electrical, mechanical, sensing, and civil engineering as well as material science and archaeology concerned with quality control and fault analysis.
