This book was released on 2007 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study to create a MATLAB simulation that models a synthetic aperture radar system with the ability to image stationary and moving point targets in a two-dimensional plane. High resolution imaging is expected to be achieved using the range Doppler algorithm. In addition to imaging point targets, slowly moving targets will be tracked using a Kalman filter in order to maintain surveillance and predict future locations.

Download or read book Automatic Target Cueing and Operator Performance with Enhanced APG-70 Synthetic Aperture Radar Imagery written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study examined automatic target cueing (ATC) and target localization performance using 4 ft resolution synthetic aperture radar (SAR) imagery collected during the Theater Missile Defense Eagle Smart Sensor ATC (TESSA) program at Eglin Air Force Base, FL. Twelve observers viewed 360 SAR images that varied in terms of aiding (unaided versus aided) and the amount and type of background foliage ("open," "treeline, " and "sparse" sites). All images contained the target to be detected, a transporter-erector-launcher (TEL), as well as two support vehicles. In the aided condition, each image was presented with four cue boxes to identify the ATC's target designations. The same set of 180 images was also presented in a separate unaided block without cues. After viewing each SAR patch map, participants identified the location of the TEL and rated their confidence in their decision. Overall, ATC cueing at the 4 ft resolution enhanced operators' confidence in their decision making but did not alter their localization accuracy, perceptual sensitivity (d'), or speed relative to the unaided condition. Further analysis revealed, however, that a critical determinant of operator performance and confidence was the "reliability" of the ATC. If all of the ATC's cues were false alarms, performance was worse than if no aiding had been provided at all. On the other hand, performance was most effective when the majority of the cues were centered over man-made vehicles. Finally, clutter in the form of background foliage degraded localization accuracy, sensitivity, reaction time, and operator confidence. As revealed by the present findings, when unaided performance is exacerbated by factors such as high background clutter, the assistance of a reliable ATC may be most beneficial.

Available in PDF, EPUB and Kindle. Book excerpt: This book chiefly addresses the analysis and design of geosynchronous synthetic aperture radar (GEO SAR) systems, focusing on the algorithms, analysis, methods used to compensate for ionospheric influences, and validation experiments for Global Navigation Satellite Systems (GNSS). Further, it investigates special problems in the GEO SAR context, such as curved trajectories, the Earth’s rotation, the ‘non-stop-and-go’ model, high-order Doppler parameters, temporal-variant ionospheric errors etc. These studies can also be extended to SAR with very high resolution and long integration time. Given the breadth and depth of its coverage, scientists and engineers in SAR and advanced graduate students in related areas will greatly benefit from this book.

Available in PDF, EPUB and Kindle. Book excerpt: Current active imaging algorithms for moving targets suffer from issues of incorrect positions (spatial) and streaking artifacts (temporal). Using the Cheney/Borden procedure, we investigated combining the spatial, temporal, and spectral aspects of real and synthetic aperture radar images. We code the Cheney/Borden algorithm to include the target velocity, include an appropriate threshold, and illustrate how multistatic radar can determine a target's location in phase space. By running simulations on single and multiple moving targets, we showed that an iteration of velocity and position choices for targets enhanced the correlation map for multistatic radar systems.

Download or read book A New Target Detector Based on Geometrical Perturbation Filters for Polarimetric Synthetic Aperture Radar (POL-SAR) written by Armando Marino and published by Springer Science & Business Media. This book was released on 2012-01-25 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a groundbraking methodology for the radar international community. The detection approach introduced, namely perturbation analysis, is completey novel showing a remarkable capability of thinking outside the box. Perturbation analysis is able to push forward the performance limits of current algorithms, allowing the detection of targets smaller than the resolution cell and highly embedded in clutter. The methodology itself is extraordinary flexibe and has already been used in two other large projects, funded by the ESA (European Space Agency): M-POL for maritime surveillance, and DRAGON-2 for land classification with particular attention to forests. This book is a perfectly organised piece of work where every detail and perspective is taken into account in order to provide a comprehensive vision of the problems and solutions.

Available in PDF, EPUB and Kindle. Book excerpt: Modern radar imaging requires advanced Synthetic Aperture Radar (SAR) techniques in order to compensate for the low resolution typically found on airborne radars. However, the techniques used to process the data collected during SAR operation require a great deal of computation. This paper proposes a novel efficient algorithm and approach to processing the data collected to quickly get high-resolution approximations for the locations of non-moving targets.

This book was released on 1995 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Target detection is a high priority of the Air Force for the purpose of reconnaissance and bombardment. This research investigates and develops methods to distinguish ground targets from clutter (i.e. foliage, landscape etc.) in Wide Angle Synthetic Aperture Radar (WASAR) images. WASAR uses multiple aspect angle SAR images of the same target scene. The WASAR data was generated from a pre-release software package (XPATCH-ES) provided by the sponsor (WL-AARA). A statistical analysis and feature extraction is performed on the XPATCH-ES data. Polarimetric and wide angle covariance matrices are estimated and analyzed. From an analysis of the wide angle covariance matrix it is shown that natural clutter has in general a uniform radar return for changing aspect angles, whereas the radar return for a target varies. Based on this analysis, two new wide angle algorithms, the WASAR Whitening Filter and the Adaptive WASAR Whitening Filter (AWWF) are developed. The target detection performance of polarimetric and multi aspect angle image combining algorithms are quantified using Receiver Operating Characteristic curves and target to clutter ratios. It is shown that wide angle processing provides superior target detection performance over polarimetric processing. Combinations of wide angle and polarimetric algorithms were used to achieve a 13.7 dB processing gain in target to clutter ratio when compared to unprocessed images of the target scene. This represents a significant improvement in target detection capabilities.
