Download or read book DURIP Integrated Sensing and Computation for Passive Covert Radar Signals Intelligence and Other Applications Driven by Moore s Law written by and published by . This book was released on 2005 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passive radar systems employing "illuminators of opportunity" such as commercial television and FM radio signals instead of dedicated radar transmitters have been the subject of increasing interest over the past decade. Under the subject contract funds, components for a flexible passive radar testbed were purchased that allow the exploration of many different passive radar architectures over a wide range of frequencies, from the lower VHF TV band (around 50 MHz) to the lower cell phone band (almost to 1 GHz). Particular emphasis is placed on multiple-antenna passive radar systems employing beamforming, i.e. not just two-antenna interferometry, since beamforming passive radar systems have not been previously explored in academic settings. Extensive technical detail on the components is given, so that this report may also serve as a "user's manual" for the system.

Download or read book Compressive Sensing for Urban Radar written by Moeness Amin and published by CRC Press. This book was released on 2017-12-19 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the emergence of compressive sensing and sparse signal reconstruction, approaches to urban radar have shifted toward relaxed constraints on signal sampling schemes in time and space, and to effectively address logistic difficulties in data acquisition. Traditionally, these challenges have hindered high resolution imaging by restricting both bandwidth and aperture, and by imposing uniformity and bounds on sampling rates. Compressive Sensing for Urban Radar is the first book to focus on a hybrid of two key areas: compressive sensing and urban sensing. It explains how reliable imaging, tracking, and localization of indoor targets can be achieved using compressed observations that amount to a tiny percentage of the entire data volume. Capturing the latest and most important advances in the field, this state-of-the-art text: Covers both ground-based and airborne synthetic aperture radar (SAR) and uses different signal waveforms Demonstrates successful applications of compressive sensing for target detection and revealing building interiors Describes problems facing urban radar and highlights sparse reconstruction techniques applicable to urban environments Deals with both stationary and moving indoor targets in the presence of wall clutter and multipath exploitation Provides numerous supporting examples using real data and computational electromagnetic modeling Featuring 13 chapters written by leading researchers and experts, Compressive Sensing for Urban Radar is a useful and authoritative reference for radar engineers and defense contractors, as well as a seminal work for graduate students and academia.
Download or read book Advances in Adaptive Radar Detection and Range Estimation written by Chengpeng Hao and published by Springer. This book was released on 2022-12-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and systematic framework for the design of adaptive architectures, which take advantage of the available a priori information to enhance the detection performance. Moreover, this framework also provides guidelines to develop decision schemes capable of estimating the target position within the range bin. To this end, the readers are driven step-by-step towards those aspects that have to be accounted for at the design stage, starting from the exploitation of system and/or environment information up to the use of target energy leakage (energy spillover), which allows inferring on the target position within the range cell under test.In addition to design issues, this book presents an extensive number of illustrative examples based upon both simulated and real-recorded data. Moreover, the performance analysis is enriched by considerations about the trade-off between performances and computational requirements.Finally, this book could be a valuable resource for PhD students, researchers, professors, and, more generally, engineers working on statistical signal processing and its applications to radar systems.

Download or read book Nebraska written by Kwame Dawes and published by U of Nebraska Press. This book was released on 2019-10-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kwame Dawes is not a native Nebraskan. Born in Ghana, he later moved to Jamaica, where he spent most of his childhood and early adulthood. In 1992 he relocated to the United States and eventually found himself an American living in Lincoln, Nebraska. In Nebraska, this beautiful and evocative collection of poems, Dawes explores a theme constant in his work—the intersection of memory, home, and artistic invention. The poems, set against the backdrop of Nebraska’s discrete cycle of seasons, are meditative even as they search for a sense of place in a new landscape. While he shovels snow or walks in the bitter cold to his car, he is engulfed with memories of Kingston, yet when he travels, he finds himself longing for the open space of the plains and the first snowfall. With a strong sense of place and haunting memories, Dawes grapples with life in Nebraska as a transplant. Purchase the audio edition.

This book was released on 2019-09-02 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today’s cyber defenses are largely static allowing adversaries to pre-plan their attacks. In response to this situation, researchers have started to investigate various methods that make networked information systems less homogeneous and less predictable by engineering systems that have homogeneous functionalities but randomized manifestations. The 10 papers included in this State-of-the Art Survey present recent advances made by a large team of researchers working on the same US Department of Defense Multidisciplinary University Research Initiative (MURI) project during 2013-2019. This project has developed a new class of technologies called Adaptive Cyber Defense (ACD) by building on two active but heretofore separate research areas: Adaptation Techniques (AT) and Adversarial Reasoning (AR). AT methods introduce diversity and uncertainty into networks, applications, and hosts. AR combines machine learning, behavioral science, operations research, control theory, and game theory to address the goal of computing effective strategies in dynamic, adversarial environments.

Download or read book Design of a Space Borne Autonomous Infrared Tracking System written by Matthew B. Kimsal and published by . This book was released on 2004-03 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complete characterization of the space environment in support of the United States goal of space Situational Awareness is not currently achievable. When confronted with recent increases in the deployment and miniaturization of microsatellites by numerous nations, the questions of foreign space capabilities are magnified. This study sought to determine the feasibility of and experimentally demonstrate a microsatellite capability to autonomously loiter about and track a target satellite. Various methods of passive remote sensing were investigated to determine the best means of detecting and tracking a target in space. Microbolometer-based infrared sensors were identified as the best alternative. A representative system was constructed for demonstration in AFIT s SIMSAT laboratory. Software modeling results identified open-loop instability, and therefore the requirement for closed-loop control. A simple PD control algorithm served as the basis for control, and a pseudo-feed-forward term was added to improve results. The feed-forward term was derived form orbital dynamics as the rate at which the chase satellite traverses around an ellipse formed in the target s frame of reference. Reduction in pointing errors of up to 67% were found in simulations. Successful non-optimal tracking results were obtained in the laboratory with a hardware-in-the-loop model for both step and moving inputs.
Download or read book Coplanar Air Launch with Gravity Turn Launch Trajectories written by David W. Callaway and published by . This book was released on 2004-03-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the feasibility of launching a vehicle based on the Boeing AirLaunch System in a coplanar, direct to rendezvous trajectory with gravity-turn. The focus of the research was to model the launch trajectory and determine the ability to reach different coplanar orbits. The launch trajectory was modeled using two-dimensional equations of motion and a boundary value problem was posed and solved for the gravity-turn trajectory. Trajectories were then created in an attempt to reach different altitudes through coasting and transfer orbits. Finally a specific orbital altitude was chosen and the trajectories were analyzed to find the most efficient route to the target orbit for fuel and time.
