Book excerpt: BISTATIC SAR DATA PROCESSING ALGORITHMS Synthetic Aperture Radar (SAR) is critical for remote sensing. It works day and night, in good weather or bad. Bistatic SAR is a new kind of SAR system, where the transmitter and receiver are placed on two separate platforms. Bistatic SAR is one of the most important trends in SAR development, as the technology renders SAR more flexible and safer when used in military environments. Imaging is one of the most difficult and important aspects of bistatic SAR data processing. Although traditional SAR signal processing is fully developed, bistatic SAR has a more complex system structure, so signal processing is more challenging. Focusing on imaging aspects of bistatic SAR signal processing, this book covers resolution analysis, echo generation methods, imaging algorithms, imaging parameter estimation, and motion compensation methods. Gives a general and updated framework for image formation using signal processing aspects Starts with an introduction to traditional SAR before moving on to more advanced topics Offers readers a range of exhaustive tools to process signals and form images Provides a solid reference for the imaging of other complicated SAR MATLAB® codes are available from the book’s companion site The book is ideal for researchers and engineers in SAR signal and data processing, as well as those working in bistatic and multistatic radar imaging, and in the radar sciences. Graduate students with a background in radar who are interested in bistatic and multistatic radar will find this book a helpful reference.

Book Synopsis Signal Processing Strategies for Bistatic Synthetic Aperture Radar by : Brian D. Rigling

Download or read book Signal Processing Strategies for Bistatic Synthetic Aperture Radar written by Brian D. Rigling. This book was released on 2003. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Recent developments in unmanned aerial vehicle (UAV) technology are spurring new interest in the fields of bistatic and multistatic synthetic aperture radar (SAR). This dissertation develops the theory necessary to extract useful information from bistatic and multistatic SAR phase history data. The approach taken in this work involves generalization of several existing monostatic SAR signal processing algorithms. A model for bistatic SAR data collection is introduced, and based on this model, a maximum likelihood algorithm for nonparametric scene reconstruction, or image formation, is proposed. This method is commonly known as matched filtering. By deriving a bistatic far-field assumption, the matched filtering algorithm may be approximated by a bistatic formulation of the common polar format algorithm. The polar format algorithm has complexity O(N2 log2 N), versus the O(N4) complexity of the matched filtering algorithm. The effect of platform motion measurement errors on bistatic SAR imagery are examined. Requirements on inertial navigation accuracy are derived, and it is shown that autofocus algorithms for monostatic SAR may applied to properly formatted bistatic SAR data. Design of nonlinear receiver flight paths, with the goal of preserving and reconstructing three-dimensional scene information, is considered. Parametric models for the three-dimensional bistatic responses from canonical scattering centers are proposed and validated against high-frequency simulation results. Lastly, algorithms for three-dimensional surface reconstruction from multistatic SAR data are proposed, based on existing theory for monostatic stereo SAR and interferometric processing. A theoretical framework for predicting the performance of these algorithms is suggested.

Download or read book Bistatic SAR / GISAR / FISAR Geometry, Signal Models and Imaging Algorithms written by Andon Dimitrov Lazarov. This book was released on 2014-01-07. Available in PDF, EPUB and Kindle. Book excerpt: Bistatic radar consists of a radar system which comprises a transmitter and receiver which are separated by a distance comparable to the expected target distance. This book provides a general theoretical description of such bistatic technology in the context of synthetic aperture, inverse synthetic aperture and forward scattering radars from the point of view of analytical geometrical and signal formation as well as processing theory. Signal formation and image reconstruction algorithms are developed with the application of high informative linear frequency and phase code modulating techniques, and numerical experiments that confirm theoretical models are carried out. The authors suggest the program implementation of developed algorithms. A theoretical summary of the latest results in the field of bistatic radars is provided, before applying an analytical geometrical description of scenarios of bistatic synthetic aperture, inverse synthetic aperture and forward scattering radars with cooperative and non-cooperative transmitters. Signal models with linear frequency and phase code modulation are developed, and special phase modulations with C/A (coarse acquisition) and P (precision) of GPS satellite transmitters are considered. The authors suggest Matlab implementations of all geometrical models and signal formation and processing algorithms. Contents 1. Bistatic Synthetic Aperture Radar (BSAR) Survey. 2. BSAR Geometry. 3.
