Download or read book Low Angle Radar Land Clutter written by J. Barrie Billingsley and published by William Andrew. This book was released on 2002-04-01 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: A necessary reference for all radar engineers or analysts including many levels of managers, advisors and decision makers in the U.S. and worldwide radar industry. Directly useful in both military (DOD) and civilian (FAA) applications. The result of 20 years of research at MIT Lincoln Lab, this book is of the most significant tehcnological consequence for the industry. It actually solves the problem of low angle radar land clutter by showing the reader how to design and predict the performance of radars that operate in situations where land clutter prevalent. Radar land clutter constitutes the unwanted radar echoes returned from the earth's surface that compete against and interfere with the desired echoes returned by targets such as aircraft and other moving and stationary targets. The ability to accurately predict the effects of land clutter in surface radar has been an unsolved problem for many years. This book is comprehensive in addressing the topic, containing many interrelated results, each important in its own right. It unifies and integrates all the results so as to create a comprehensive, innovative, and unequaled work. The results of this book directly enable the reader to predict land clutter effects in surface radar. Modern military aircraft deliberately fly low to hide their presence from radars that are also dealing with land clutter. Depending on the terrain, the performance of the radar varies greatly from very good to very poor. This book helps radar engineers provide accurate assessments of ground clutter, thus bringing their ability to detect and operate against low flying aircraft to a much higher and much more consistent level.

Download or read book Alternatives for Landmine Detection written by Jacqueline MacDonald Gibson and published by Rand Corporation. This book was released on 2003 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the rate that government and nongovernmental organizations are clearing existing landmines, it will take 450-500 years to rid the world of them. Concerned about the slow pace of demining, the Office of Science and Technology asked RAND to assess potential innovative technologies being explored and to project what funding would be required to foster the development of the more promising ones. The authors of this report suggest that the federal government undertake a research and development effort to develop a multisensor mine detection system over the next five to eight years.
Download or read book Synthetic Aperture Radar Polarimetry written by Jakob J. van Zyl and published by John Wiley & Sons. This book was released on 2011-10-14 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the application of polarimetric synthetic aperture radar to earth remote sensing based on research at the NASA Jet Propulsion Laboratory (JPL). This book synthesizes all current research to provide practical information for both the newcomer and the expert in radar polarimetry. The text offers a concise description of the mathematical fundamentals illustrated with many examples using SAR data, with a main focus on remote sensing of the earth. The book begins with basics of synthetic aperture radar to provide the basis for understanding how polarimetric SAR images are formed and gives an introduction to the fundamentals of radar polarimetry. It goes on to discuss more advanced polarimetric concepts that allow one to infer more information about the terrain being imaged. In order to analyze data quantitatively, the signals must be calibrated carefully, which the book addresses in a chapter summarizing the basic calibration algorithms. The book concludes with examples of applying polarimetric analysis to scattering from rough surfaces, to infer soil moisture from radar signals.

Download or read book Radar Detection Theory of Sliding Window Processes written by Graham Weinberg and published by CRC Press. This book was released on 2017-09-27 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constant false alarm rate detection processes are important in radar signal processing. Such detection strategies are used as an alternative to optimal Neyman-Pearson based decision rules, since they can be implemented as a sliding window process running on a radar range-Doppler map. This book examines the development of such detectors in a modern framework. With a particular focus on high resolution X-band maritime surveillance radar, recent approaches are outlined and examined. Performance is assessed when the detectors are run in real X-band radar clutter. The book introduces relevant mathematical tools to allow the reader to understand the development, and follow its implementation.

Download or read book Radar Meteorology written by S. Raghavan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we all know, weather radar came into existence during the Second World War when aircraft detection radars had their vision limited by echoes from rain bearing clouds. What was often considered to be of nuisance value by the air force personnel trying to locate enemy aircraft was seen as an opportunity by the weather men. Thus adversity in one field was converted into an opportunity in another. Since then weather radar has found myriad applications with the increased sophistication of technology and processing systems. It has now become an indispensable tool for the operational forecasters, cloud physicists and atmospheric scientists. The current generation radar is but a distant echo of the radars of the 1940s. As a result, its operation and maintenance have become very complex, like the technology it uses. Therefore, there is a definite requirement of focussing our special attention not only on the science of radar meteorology but also on its operational aspects. The present book, as pointed out by the author, attempts to fill this gap. The author has presented the subject with a balanced blend of science, technology and practice. The canvas is indeed very broad. Starting with the history of weather radar development the book goes on to discuss in a lucid style the physics of the atmosphere related to radar observation, radar technology, echo interpretation, different applications and finally attempts to look into the future to indicate potential new opportunities in this field.
