Synthetic aperture radar (SAR) is a well-known remote sensing technique, but conventional single-antenna SAR is inherently limited by the minimum antenna area constraint. Although there are still technical issues to overcome, multi-antenna SAR offers many benefits, from improved system gain to increased degrees-of-freedom and system flexibility. Multi-Antenna Synthetic Aperture Radar explores the potential and challenges of using multi-antenna SAR in microwave remote sensing applications. These applications include high-resolution imaging, wide-swath remote sensing, ground moving target indication, and 3-D imaging. The book pays particular attention to the signal processing aspects of various multi-antenna SAR from a top-level system perspective.

Explore Recent Extensions of Synthetic Aperture Radar Systems The backbone of the book is a series of innovative microwave remote sensing approaches developed by the author. Centered around multi-antenna SAR imaging, these approaches address specific challenges and potential problems in future microwave remote sensing. Chapters examine single-input multiple-output (SIMO) multi-antenna SAR, including azimuth and elevation multi-antenna SAR, and multiple-input multiple-output (MIMO) SAR. The book details the corresponding system scheme, signal models, time/phase/spatial synchronization methods, and high-precision imaging algorithms. It also investigates their potential applications.

Introductory Tutorials and Novel Approaches in Multi-Antenna SAR Imaging Rigorous and self-contained, this is a unique reference for researchers and industry professionals working with microwave remote sensing, SAR imaging, and radar signal processing. In addition to novel approaches, the book also presents tutorials that serve as an introduction to multi-antenna SAR imaging for those who are new to the field.

Reviews for Multi-Antenna Synthetic Aperture Radar

... a comprehensive and valuable resource for graduate students, academics, and practitioners actively pursuing research in SAR. -Abduwasit Ghulam, Assistant Professor, Center for Sustainability, St. Louis University, Missouri, USA, from Photogrammetric Engineering & Remote Sensing, September 2015 A new world is opening, full of a huge amount of new, attractive, and useful applications. But a new science is needed to support the necessary vision to explore and utilize the available opportunities therein contained. The book, Multi-Antenna Synthetic Aperture Radar, is just the important necessary step in this direction, formalizing the full theory of use of multiple antennas in SAR systems, together with the appropriate novel software codes for the raw data processing. ... The book presents an exhaustive preliminary formalization of this new science, and will play a very important role for its future development. ... The book contains all the current developments of SAR procedures and techniques, including improvement of features, extension of applications, three-dimension and moving-target imaging, and other attractive new performances. ... The book is very valuable for SAR operators who want to update their backgrounds in the area of hardware and software extensions of SAR techniques. -Giorgio Franceschetti, University Federico II of Napoli, Italy
