Spectral Characteristics of Low angle Radar Ground Clutter

Author:
Publisher:
ISBN: OCLC:932958702
Release Date: 1989
Genre:

The performance of ground-based radars is affected by the spectral characteristics of ground clutter. Most signal processing algorithms designed to enhance detection performance are Doppler-frequency-sensitive, such as the moving target indicator filter, Doppler processor and coherent clutter map. This report gives the results of a comprehensive spectral analysis of low-angle ground clutter, using the MIT Lincoln Laboratory Phase I data and the DREO S-band clutter data. The report presents the spectral analysis of ground clutter for different bands of radar frequency; describes the data used in the spectral analysis, including both the conventional Fourier analysis and a super-resolution spectral analysis technique; gives a brief background on the maximum entropy spectral estimate; and describes the particular procedure designed to bring out the spectral characteristics of ground clutter from short time series.

Radar Principles for the Non Specialist

Author: John C. Toomay
Publisher: Springer Science & Business Media
ISBN: 9789401169851
Release Date: 2012-12-06
Genre: Juvenile Nonfiction

What This Book Is This book is about radar. It will teach you the essentials of radar, the underlying principles. It is not like an engineering handbook which pro vides detailed design equations without explaining either derivation or rationale. It is not like a graduate school textbook which may be abstruse and esoteric to the point of incomprehensibility. And it is not like an anthology of popular magazine articles which may be gaudy but superfi cial. It is an attempt to distill the very complex, rich technology of radar into its fundamentals, tying them to the laws of nature on one end and to the most modern and complex systems on the other. Who It's For If your work requires you to supervise or meet as coequals with radar systems engineers or designers, this book will allow you to understand them, to question them intelligently and perhaps to provide them with a perspective (a dispassionate yet competent view) that they lack. If you are trained in another discipline but have been made the man ager of a radar project or a system program that has one or more radars as sub-systems, this book will provide you with the tools you need, not only to give your team members confidence, but also to make a substantive technical contribution yourself.

Publisher: Springer Science & Business Media
ISBN: 3540003282
Release Date: 2005-07-06
Genre: Science

With their images practically ubiquitious in the daily media, weather radar systems provide data not only for understanding weather systems and improving forecasts (especially critical for severe weather), but also for hydrological applications, flood warnings and climate research in which ground verification is needed for global precipitation measurements by satellites. This book offers an accessible overview of advanced methods, applications and modern research from the European perspective. An extensive introductory chapter summarizes the principles of weather radars and discusses the potential of modern radar systems, including Doppler and polarisation techniques, data processing, and error-correction methods. Addressing both specialist researchers and nonspecialists from related areas, this book will also be useful for graduate students planning to specialize in this field

Multifrequency Measurements of Radar Ground Clutter at 42 Sites Volume 2 Appendices A Through D

Author:
Publisher:
ISBN: OCLC:227777677
Release Date: 1991
Genre:

This report determines how ground clutter strength varies with RF frequency from VHF to X-Band in ground sited radar. This determination is accomplished by providing extensive empirical results from multifrequency clutter measurements conducted at 42 different sites widely dispersed over the North American continent. These results indicate that the frequency dependence of ground clutter strength depends upon terrain type and can vary, for example, from a strongly decreasing function of frequence in forest to a strongly increasing function of frequency in farmland. Five major terrain categories are defined that encompass this dependence, namely, urban, mountain, forest, farmland and desert. Within each terrain category results are also shown to be dependent upon the relief or roughness of the terrain and upon the depression angle at which the terrain is illuminated. The depression angle dependence is important even for the very low angles and small variations in angle that occur in ground-sited radar. This report presents specific clutter strength results at each of five frequencies (VHF, UHF, L-, S- and X-band) from each of 42 sites at which measurements were conducted. The report then combines results from similar sites to obtain the general dependence of clutter strength versus frequency for each terrain category.

Sabres Over MiG Alley

Author: Kenneth P. Werrell
Publisher: Naval Institute Press
ISBN: 9781612513447
Release Date: 2013-06-11
Genre: History

This is the story of the first jet versus jet war, the largest in number of victories and losses, and one of the few military bright spots in the Korean War. It tells how an outnumbered force of F-86 Sabres limited by range and restricted by the rules of engagement, decisively defeated its foe. Based on the latest scholarship, author Kenneth Werrell uses previously untapped sources and interviews with sixty former F-86 pilots to explore new aspects of the subject and shed light on controversies previously neglected. For example, he found much greater violation of the Yalu River than thus far has appeared in the published materials. The F-86 became a legend in "The Forgotten War" because of its performance and beauty, but most of all, because of its record in combat.

Weather Radar Technology Beyond NEXRAD

Author: National Research Council
Publisher: National Academies Press
ISBN: 9780309169455
Release Date: 2002-07-31
Genre: Science

Weather radar is a vital instrument for observing the atmosphere to help provide weather forecasts and issue weather warnings to the public. The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of the United States (NRC, 1995). This network was designed in the mid 1980s and deployed in the 1990s as part of the National Weather Service (NWS) modernization (NRC, 1999). Since the initial design phase of the NEXRAD program, considerable advances have been made in radar technologies and in the use of weather radar for monitoring and prediction. The development of new technologies provides the motivation for appraising the status of the current weather radar system and identifying the most promising approaches for the development of its eventual replacement. The charge to the committee was to determine the state of knowledge regarding ground-based weather surveillance radar technology and identify the most promising approaches for the design of the replacement for the present Doppler Weather Radar. This report presents a first look at potential approaches for future upgrades to or replacements of the current weather radar system. The need, and schedule, for replacing the current system has not been established, but the committee used the briefings and deliberations to assess how the current system satisfies the current and emerging needs of the operational and research communities and identified potential system upgrades for providing improved weather forecasts and warnings. The time scale for any total replacement of the system (20- to 30-year time horizon) precluded detailed investigation of the designs and cost structures associated with any new weather radar system. The committee instead noted technologies that could provide improvements over the capabilities of the evolving NEXRAD system and recommends more detailed investigation and evaluation of several of these technologies. In the course of its deliberations, the committee developed a sense that the processes by which the eventual replacement radar system is developed and deployed could be as significant as the specific technologies adopted. Consequently, some of the committee's recommendations deal with such procedural issues.
