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.

Antennas are part of every radar, every communications system, and every electronic warfare system. Therefore antennas are an important technical subject. The number of antenna books that have been published in the last 5 years alone attest to this fact. But why another book about antennas? What does this book offer that is different from all the others? The answer is: accessibility. Most of the technical literature on antennas is written for those with extensive backgrounds in electromagnetic theory and familiarity with the mathematical language of vector analysis, differential equations, and special functions. This puts much of the antenna literature out of reach for the nonspecialist who needs to understand the subject but cannot afford the time required to become familiar with all the background material. With the rapid expansion of technical knowledge, the number of engi neering students who find themselves attracted to "classical" subjects, such as electromagnetic theory, is on the decline, making it increasingly difficult to train engineers in areas involving antennas. Some authors in other technical fields have recognized this problem. For example, books on solid-state elec tronic devices that do not require an extensive background in quantum me chanics are available, useful, and informative. This book fulfills a similar Ileed in the area of antennas.
