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 The Radar Range Equation for the Detection of Steady Targets in Weibull Clutter written by Leon C. Rountree and published by . This book was released on 1990 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the detection characteristics of a steady target immersed in radar clutter characterized by returns statistically modeled according to a Weibull probability density function are developed. A detector model is developed by modifying an envelope detection scheme used to detect deterministic signals in Gaussian noise. By examining the statistics of the detector output under alternate hypotheses, an expression for the probability of detection (P sub d) is developed in terms of the probability of false alarm (P sub fa), the signal-to-clutter ratio (SCR), and the Weibull skewness parameter (b), which is a function of the type of terrain causing the clutter. This expression is used in conjunction with a form of the radar range equation for area clutter to describe the relationship between p sub d, p sub fa, SCR, b, and the radar detection range. This relationship involves Marcum's Q sub d function and an algorithm is presented which evaluates this function. The algorithm is a series approximation, also presented as a recursive relationship, that can be computed to a desired precision. Plots of P sub d versus SCR and P sub d versus range are developed for various values of p sub fa and b. The plots provide a means of evaluating the detector performance and predicting the radar detection range for several values of b.

Book excerpt: The second edition of Sea Clutter: Scattering, the K Distribution and Radar Performance gives an authoritative account of our current understanding of radar sea clutter. Topics covered include the characteristics of radar sea clutter, modelling radar scattering by the ocean surface, statistical models of sea clutter, the simulation of clutter and other random processes, detection of small targets in sea clutter, imaging ocean surface features, radar detection performance calculations, CFAR detection, and the specification and measurement of radar performance. The calculation of the performance of practical radar systems is presented in sufficient detail for the reader to be able to tackle related problems with confidence. For this fully revised and updated second edition new material has been added on the Doppler characteristics of sea clutter and associated detection processing methods, bistatic sea clutter measurements; electromagnetic scattering theory of littoral sea clutter and bistatic sea clutter; the use of models for predicting radar performance, including discussion of Lognormal and Weibull models; further results and extended discussion on the modelling of the K distribution shape parameter for different conditions; the simulation of Doppler spectra of sea clutter; high grazing angle scattering; and the use of the K distribution in other fields. The material has been reorganized into four parts: Sea Clutter Properties, Mathematics of the K distribution, Radar Detection and Physical Modelling. This reorganization allows readers to access specific areas quickly, without the need for an extensive knowledge of the other parts.

Available in PDF, EPUB and Kindle. Book excerpt: This highly-anticipated second edition of an Artech House classic covers several key radar analysis areas: the radar range equation, detection theory, ambiguity functions, waveforms, antennas, active arrays, receivers and signal processors, CFAR and chaff analysis. Readers will be able to predict the detection performance of a radar system using the radar range equation, its various parameters, matched filter theory, and Swerling target models. The performance of various signal processors, single pulse, pulsed Doppler, LFM, NLFM, and BPSK, are discussed, taking into account factors including MTI processing, integration gain, weighting loss and straddling loss. The details of radar analysis are covered from a mathematical perspective, with in-depth breakdowns of radar performance in the presence of clutter.
