This book offers an overview of modern advances in Ground Penetrating Radar (GPR) for the reader hoping to understand comprehensive electromagnetic culture, combining instrumental development of radar, signal processing, imaging, and calibration/correction of measured data.

GPR has a multi-disciplinary character that can bring together a diverse and broad community. Of concern are the design and optimization of innovative radars, by virtue of the antennas and associated electronics, imaging algorithms, methodological diversity, calibration procedures, and the development of tools for the interpretation of data in mono-static or multi-static configurations within frequency or transient domains.

This book provides illustrations in civil engineering for the diagnosis of transport infrastructures and buildings, archeological surveys for the appreciation of cultural heritage, detection of underground pipes and cavities, estimation of soil water content for agriculture, and mapping of root trees developing underground, and in planetology, the analysis of the internal structure of planets and other celestial bodies through electromagnetic waves.

Mohammed Serhir is Associate Professor at CentraleSupélec, Gif-sur-Yvette, and is part of SONDRA CentraleSupélec ONERA NUS DSO Research Alliance in France. His research interests include GPR, microwave imaging, antenna design, modeling, and measurement in harmonic and time domains.

Dominique Lesselier is CNRS Director of Research Emeritus, Laboratoire des Signaux et Systèmes, Gif-sur-Yvette, jointly at Université Paris-Saclay, CNRS and CentraleSupélec in France. His research interests include the development of solutions to inverse problems and imaging methods, encompassing mathematics, numerics, and applications.
