Description

Inverse Synthetic Aperture Radar Imaging: Principles, Algorithms and Applications is based on the latest research on ISAR imaging of moving targets and non-cooperative target recognition (NCTR).

With a focus on the advances and applications, this book will provide readers with a working knowledge on various algorithms of ISAR imaging of targets and implementation with MATLAB. These MATLAB algorithms will prove useful in order to visualize and manipulate some simulated ISAR images.  

Key topics include;

  • basic principles of radar backscattering, radar imaging, and signal analysis
  • the characteristics of radar returns from targets
  • how to produce well-focused ISAR images of moving targets
  • features that can extracted from ISAR images
  • several important algorithms are introduced for ISAR image formation, ISAR image auto-focusing, and applications of ISAR imaging to air targets, sea vessels and ground moving targets
  • examples of ISAR imaging of ground moving targets, air targets, and sea vessels are discussed in detail

Reviews:

"This new text is an excellent addition to the radar literature for both students and experienced practitioners. Both Dr Chen and Prof. Martorella are mature lecturers, and this shows in the development of the algorithms from the basic physics to the advanced radar applications. Most importantly, their MATLAB code closely follows the chapters, and demystifies the science. This text can be equally used for both graduate level courses and for development of radar applications in industry.Mark E Davis, Life Fellow IEEE, Prospect NY USA
 

About the Authors

Victor C. Chen is internationally recognized for his work on radar micro-Doppler signatures and time frequency analysis. Dr. Chen received a Ph.D. in Electrical Engineering from Case Western Reserve University, Ohio. Since 1982, he has worked with several companies in the United States and the Radar Division at the U.S. Naval Research Laboratory in Washington, D.C. He has worked on ISAR imaging, time-frequency analysis for radar signal and imaging, and radar micro-Doppler signature analysis. He has published more than 150 papers in journals and proceedings. He has authored, co-authored, and edited several books, including Time-Frequency Transforms for Radar Imaging and Signal Analysis (Artech House, 2002) and The micro-Doppler Effect in Radar (Artech House, 2011). Dr. Chen is a Fellow of the Institute of Electrical and Electronics Engineers.

Marco Martorella is a Professor at the Department of Information Engineering of the University of Pisa and an external Professor at the University of Cape Town where he leads lectures on high resolution and imaging radar within the Masters in Radar and Electronic Defence course. He is author of more than 120 international journal and conference papers and three book chapters. He has presented several tutorials and short courses on ISAR at international radar conferences and in several research institutions in US, Australia, South Africa and Europe. He is a member of the IET Radar Sonar and Navigation Editorial Board and chair of the NATO SET-196 on multichannel/multistatic radar imaging of noncooperative targets. He has been recipient of the IEEE 2013 Fred Nathanson Memorial Radar Award.
