Imaging radars, specifically Synthetic Aperture Radar [SAR], are able to provide images of the Earth's surface with a spatial resolution comparable to that of the newest and most performing optical systems, but with the advantage of sun independence and operation in almost any meteorological condition. The feature of allowing systematic acquisitions and the recent advances in the applications to natural risk monitoring and security have driven the technology into what has been called the "golden age of SAR". Multi-Dimensional Imaging with Synthetic Aperture Radar provides a comprehensive description of the principles, models, and data processing methodologies underlying the development of recent SAR applications regarding f.i., topographic mapping and natural risk situational awareness (seismic-tectonics, active volcano, landslides, subsidence, urban monitoring and infrastructure control]. The hook is intended to serve as a reference for scholars and postgraduate students in a broad topic, embracing electromagnetism and signal processing for geoinformation and geosciences. Key Features, Addresses the principles of SAR and SAR image formation, Explains the modeling and data processing involved in interferometric and tomographic SAR, Shows the potential of the use of SAR technology in applications, Presents the link between basic signal processing concepts and state-of-the-art capabilities of imaging radars, Explains with examples basic algorithms for SARw nGianfranco Fornaro, Research Director at the Institute for Electromagnetic Sensing of the Environment (IREA), National Research Council (CNR), Naples, Italy
