Multi-Antenna Synthetic Aperture Radar
presents a
systematic review of recent developments in multi-antenna
synthetic aperture radar technology with particular
attention to the signal processing aspects of various multi-
antenna radar systems. It also provides a summary of
applications and challenges of multi-antenna synthetic
aperture radar in high-resolution imaging, wide-swath
remote sensing, ground target detection, and three-
dimensional imaging.
The book begins by defining and describing multi-
antenna synthetic aperture radar (SAR), covering basic
principles of synthetic aperture, and sampling theorem and
interpolation, point spread function, and image formation
algorithm to provide the reader with a comprehensive
understanding of the subject matter. Eleven chapters cover
topics from azimuth and elevation multi-antenna SAR
to processing algorithms, including signal models, time/
phase/spatial synchronization methods, and high-precision
imaging with tutorials on the author’s approaches. The
book is intended primarily for professionals, scientists,
and graduate students working with SAR imaging, SAR
applications, and system development. The book includes
221 black-and-white maps, photographs, and diagrams.
Following a high-level review of multi-antenna
synthetic aperture radar design concepts, advantages,
and limitations in Chapter 1, Chapter 2 presents several
basic concepts of general interest in the SAR domain,
which help the reader follow subsequent chapters. Topics
covered in Chapter 2 include convolution and correlation,
matched filtering, radar ambiguity function, principles of
SAR and SAR imaging, and related terminology. Chapters
3 and 4 introduce single-input multiple-output (SIMO)
SAR systems, including azimuth multi-antenna SAR and
elevation multi-antenna SAR. Current challenges in high-
resolution, wide-swath SAR imaging and ground moving
target detection are summarized in these chapters with
the prospects of an azimuth multi-antenna SAR-based
solution in Chapter 3 and an elevation multi-antenna
SAR-based solution in Chapter 4. Chapters 5 through 7
introduce multiple-input multiple-output (MIMO) SAR
in high-resolution and wide-swath SAR remote sensing
applications. The author discusses several waveform
diversity design methods (e.g., orthogonal frequency
diversion multiplexing chirp waveform with a large time-
bandwidth) and proposes a space-time coding SAR for
high-resolution imaging and two-antenna MIMO SAR for
ground moving target detection as efficient and improved
approaches. In Chapters 8 and 9, the author describes
concepts of spatial synchronization methods, including
direct-path signal-based, global positioning system (GPS)-
based, communication link-based approaches for time,
phase and antenna directing synchronization for spatial
synchronization. This is followed by an introduction to
baseline measurement in distributed multi-antenna SAR
systems. Chapter 10 presents image formation algorithms
with a focus on azimuth-variant Doppler characteristics
and two-dimensional point spread function. Chapter
11 summarizes the multi-antenna SAR systems and
techniques for three-dimensional imaging.
The book is founded on a broad range of multi-antenna
synthetic aperture radar theories, algorithms, literature
review, simulation studies, and application scenarios with
a series of microwave remote sensing approaches developed
by the author. It summarizes the latest advances in SAR
and describes the promising potential of three-dimensional
imaging and ground moving target detection. However,
the book seems best-suited for professionals and scientists
working on radar engineering and design. Doctoral
students may find it helpful for expanding their knowledge
of the fundamentals of SAR imaging and its applications.
