Modern airborne and spaceborne imaging radars, known as synthetic
aperture radars (SARs), are capable of producing high-quality
pictures of the earth's surface while avoiding some of the
shortcomings of certain other forms of remote imaging systems.
Primarily, radar overcomes the nighttime limitations of optical
cameras, and the cloud- cover limitations of both optical and
infrared imagers. In addition, because imaging radars use a form of
coherent illumination, they can be used in certain special modes
such as interferometry, to produce some unique derivative image
products that incoherent systems cannot. One such product is a
highly accurate digital terrain elevation map (DTEM). The most
recent (ca. 1980) version of imaging radar, known as spotlight-mode
SAR, can produce imagery with spatial resolution that begins to
approach that of remote optical imagers. For all of these reasons,
synthetic aperture radar imaging is rapidly becoming a key
technology in the world of modern remote sensing. Much of the basic
workings' of synthetic aperture radars is rooted in the concepts of
signal processing. Starting with that premise, this book explores
in depth the fundamental principles upon which the spotlight mode
of SAR imaging is constructed, using almost exclusively the
language, concepts, and major building blocks of signal processing.
Spotlight-Mode Synthetic Aperture Radar: A Signal Processing
Approach is intended for a variety of audiences. Engineers and
scientists working in the field of remote sensing but who do not
have experience with SAR imaging will find an easy entrance into
what can seem at times a very complicated subject. Experienced
radar engineers will find that the book describes several modern
areas of SAR processing that they might not have explored
previously, e.g. interferometric SAR for change detection and
terrain elevation mapping, or modern non-parametric approaches to
SAR autofocus. Senior undergraduates (primarily in electrical
engineering) who have had courses in digital signal and image
processing, but who have had no exposure to SAR could find the book
useful in a one-semester course as a reference.
