Book Synopsis Spotlight-Mode Synthetic Aperture Radar: A Signal Processing Approach by : Charles V. J. Jakowatz
Download or read book Spotlight-Mode Synthetic Aperture Radar: A Signal Processing Approach written by Charles V. J. Jakowatz. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Radar Imaging and Feature Extraction written by . This book was released on 1999. Available in PDF, EPUB and Kindle. Book excerpt: Advanced spectral estimation methods are presented for radar imaging and target feature extraction. We study problems involved in inverse synthetic aperture radar (ISAR) autofocus and imaging, synthetic aperture radar (SAR) autofocus and motion compensation, superresolution SAR image formation, three-dimensional (3-D) target feature extraction via curvilinear SAR (CLSAR), and time delay estimation. For the ISAR imaging problem, we present a parametric AUTOCLEAN (AUTOfocus via CLEAN) algorithm, and two non-parametric algorithms including an adaptive Capon and a recursive APES (Amplitude and Phase EStimation). For the problems related to SAR imaging, we propose a Semi-PARametric (SPAR) algorithm for target feature extraction and superresolution image formation, and two parametric methods, MCRELAX (Motion Compensation RELAX) and MCCLEAN (Motion Compensation CLEAN), for simultaneous target feature extraction and cross-range phase error compensation. For the 3-D target feature extraction problem, an AUTOfocus algorithm based on the RELAXation-based optimization approach (AUTORELAX) is proposed to compensate the aperture errors in CLSAR and to extract 3-D target features. For the time delay estimation problem, we first present a Weighted Fourier transform and RELAXation-based (WRELAX) approach. Then, a MODE-WRELAX (MODE (Method Of Direction Estimation) together with WRELAX) algorithm is proposed for the superresolution time delay estimation.
