Within the wide and fascinating field of radar techniques and systems, this book describes in detail a number of areas of research related to system architecture and design, phenomenology, array antennas and signal processing.

This book introduces advanced sparsity-driven models and methods and their applications in radar tasks such as detection, imaging and classification. Compressed sensing (CS) is one of the most active topics in the signal processing area. By exploiting and promoting the sparsity of the signals of interest, CS offers a new framework for reducing data without compromising the performance of signal recovery, or for enhancing resolution without increasing measurements.

Advances in Bistatic Radar updates and extends bistatic and multistatic radar developments since the publication of Willis' Bistatic Radar in 1991. New and recently declassified military applications are documented, civil applications are detailed including commercial and scientific systems and leading radar engineers provide expertise to each of these applications. Advances in Bistatic Radar consists of two major sections: Bistatic/Multistatic Radar Systems and Bistatic Clutter and Signal Processing. Starting with a history update, the first section documents the early and now declassified military AN/FPS-23 Fluttar DEW-Line Gap-filler, and high frequency (HF) bistatic radars developed for missile attack warning. It then documents the recently developed passive bistatic and multistatic radars exploiting commercial broadcast transmitters for military and civilian air surveillance. Next, the section documents scientific bistatic radar systems for planetary exploration, which have exploited data link transmitters over the last forty years; ionospheric measurements, again exploiting commercial broadcast transmitters; and 3-D wind field measurements using a bistatic receiver hitchhiking off doppler weather radars. This last application has been commercialized. The second section starts by documenting the full, unclassified bistatic clutter scattering coefficient data base, along with the theory and analysis supporting its development. The section then details two major clutter-related developments, spotlight bistatic synthetic aperture radar (SAR), which can now generate high resolution images using bistatic autofocus and related techniques; and adaptive moving target indication (MTI), which allows cancellation of nonstationary clutter generated by moving (i.e. airborne) platforms through the use of bistatic space-time adaptive processing (STAP).

Underwater communication systems have been gaining significant interest over the past two decades in addressing various applications, ranging from the depths of the ocean to its surface. To implement applications such as oil monitoring, earthquake and tsunami detection, marine animal study and military surveillance, underwater communications are crucial in establishing reliable connections between sensor nodes.

After nearly 50 years of sustained research and 30 years of operational deployment, research in weather radars has witnessed tremendous growth over the past decade and is now spilling over to novel applications and geographies. This book provides a systematic and thorough review of advances in research, developments, and technologies in the field.

Supported by 202 equations and 170 illustrations, Airborne Early Warning System Concepts is an invaluable reference tool for a wide audience. It will be a welcome library addition for the engineer, scientist, system integrator, user, designer, or manager with interest in AEW concepts. It is also suitable for students and professors of electrical and system engineering or military science. This comprehensive discussion of airborne early warning (AEW) system concepts encompasses a wide range of issues, including capabilities and limitations, developmental trends and opportunities for improvement. Consisting of contributions from experts in the field, the book is presented at varying levels of complexity, ranging from elementary to advanced. For the generalist, the text provides a fundamental understanding of the status of AEW concepts with the use of only elementary mathematics. For the specialist, there are separate chapters that emphasize key AEW radar issues.

This new book from Richard Klemm, author of the highly successful Principles of Space-time Adaptive Processing (IEE,2002), examines the various applications of space-time adaptive processing including applications in OTH-radar, ground target tracking, STAP in real world clutter environments, jammer cancellation, superresolution, active sonar, seismics and communications. Including contributions from distinguished international authors, the book provides a unique overview of the field of space-time procesing. The book is divided in two parts; the first dealing with the classical adaptive suppression of airbourne and space based radar clutter and the second comprising of miscellaneous applications in other fields such as communications, underwater sound and seismics.

The need to enhance the safety and efficiency of aviation systems has escalated with increasing aviation activity and competitiveness around the world. Weather, which is one of the principal factors affecting aviation performance, is acquiring ever more importance as aviation is poised to shift to futuristic paradigms such as free flight. Advanced systems and approaches to the surveillance of weather and the resultant generation of highly processed, detailed, accurate and reliable weather data, are becoming integral parts of support systems for navigation and air traffic management.
