We present a technique for aperture weighting for use in video synthetic aperture radar
(SAR). In video SAR the aperture required to achieve the desired cross range resolution …

Coherent sub-aperture techniques for processing synthetic aperture radar SAR signals are
described. The techniques involve partitioning the full aperture data, in either the time or the …

Abstract Synthetic Aperture Radar (SAR) is used to form images that are maps of radar
reflectivity of some scene of interest, from range soundings taken over some spatial …

A new, fast algorithm for synthetic aperture radar (SAR) image formation is introduced. The
algorithm is based on a decomposition of the time domain backprojection technique. It …

An aperture weighting algorithm, amplitude contrast enhancement (ACE), has been
developed for synthetic aperture radar (SAR). ACE uses an iterative, gradient-based …

General Atomics Aeronautical Systems, Inc.(GA-ASI) is designing a real-time, video-SAR
(synthetic aperture radar) mode for a test bed radar system. Typically, the flight path for video …

A synthetic aperture radar (SAR) is a radar sensor that provides azimuth resolution superior
to that achievable with its real beam by synthesizing a long aperture using platform motion …

The spatial extent that can be accurately imaged by a synthetic aperture radar (SAR) is
unfortunately limited. This restriction results from the fact that the number of independent …

Synthetic aperture radar (SAR) is a coherent imaging process that requires an uninterrupted
collection of Nyquist-sampled signal data. Corrupted or missing data in the collected …

Legacy synthetic aperture radar (SAR) exploitation algorithms were image-based
algorithms, designed to exploit complex and/or detected SAR imagery. In order to improve …
