Book Synopsis A Clutter Model for Space Based Radar by : Carl J. Lauer
Download or read book A Clutter Model for Space Based Radar written by Carl J. Lauer and published by . This book was released on 1983 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clutter model for a pulse doppler space based radar simulation is described. Ground clutter is represented as a random process with mean power, mean doppler, and doppler spread determined from experimental measurements and from physical and geometrical quantities pertinent to the radar location, look angle, beam pattern, etc. The above three quantities are used to define the clutter spectrum observed at a given radar range gate, and a statistical signal generation technique is employed to generate a realization or sample of the instantaneous clutter signal observed.

Book excerpt: A model for radar clutter as encountered from a space-based platform is developed. Included in the model are land, sea and airborne clutter with emphasis on land clutter. Parametric fits to existing reflectivity data are performed for seven generic terrain types: desert, forest, mountain, rural, urban, snow and ice and sea. The fits are parametric in frequency and grazing angle and, in the case of sea clutter, polarization. In addition to the mean values of clutter reflectivity, the variation about the mean is emphasized. The underlying causes of clutter variability nonhomogeneous terrain type, terrain undulation, etc., are discussed. Quantitative estimates of their effects are presented. A theory of probability density function of clutter based on the resolution cell size, correlation lengths, and underlying statistics of individual scatterers, is presented. Examples are worked out for five terrain types and a large resolution cell. The results are threshold settings required for given false alarm probabilities. Clutter spectra are discussed briefly. Finally, requirements and computer simulations are examined with particular attention to the advantages and disadvantages of three candidate measurement programs.

Book Synopsis Analysis of Space-Based Radar Clutter Spectra Over Different Types of Terrain and Their Effects on Detection Performance by : D. Faubert
Download or read book Analysis of Space-Based Radar Clutter Spectra Over Different Types of Terrain and Their Effects on Detection Performance written by D. Faubert and published by . This book was released on 1986 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer model was used to make a detailed analysis of the clutter spectra received by real aperture Space-Based Radars orbiting over different types of terrain. The influence of terrain on L-band SBR detection performance has also been studied. It was found that the clutter spectra tend to become narrower as the grazing ange of the antenna increases but that they broaden as the antenna points progressively more away from the direction of motion of the satellite. The interference caused by the clutter background is progressively higher for ice covered ground but smaller for a snow-covered terrain and the smallest for an ocean background. The minimum detectable velocities of the SBR were found to vary by a factor of up to three according to the terrain type. (Canada).

Book Synopsis Alternatives for Military Space Radar by : Joseph A. Post
Download or read book Alternatives for Military Space Radar written by Joseph A. Post and published by . This book was released on 2007 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "DoD's 2006 Quadrennial Defense Review calls for investment in such systems to grow in order to provide 'a highly persistent capability to identify and track moving ground targets in denied areas.' To that end, DoD and the National Reconnaissance Office are proposing to develop a constellation of Earth-orbiting Space Radar satellites that would provide imagery, GMTI, and geospatial intelligence products to members of the military and the intelligence community. This Congressional Budget Office (CBO) study--prepared at the request of Senators Wayne Allard and Bill Nelson in their respective capacities as the Chairman and Ranking Member of the Senate Committee on Armed Services' Subcommittee on Strategic Forces--examines the costs and potential performance of four possible designs for a Space Radar system."--Preface.

Book Synopsis Clutter-Doppler Spectral Analysis for a Space-Based Radar by :
Download or read book Clutter-Doppler Spectral Analysis for a Space-Based Radar written by and published by . This book was released on 1991 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of worst-case, ionospheric scintillation on the clutter- Doppler spectrum is analyzed for a space-based radar that operates between 100 and 1300 MHz. Analytical expressions for the spectrum are derived for a narrow, Gaussian antenna beam. For normal system parameters, the analytical expressions, combined with data from the Defense Nuclear Agency's Wideband satellite experiment, are used to compare the relative significance of the components of the clutter-Doppler spread for a range cell and to obtain the clutter-Doppler spread over the antenna's mainlobe. In addition, lower bounds are determined on the achievable reduction in the clutter-Doppler spread of a system.

Available in PDF, EPUB and Kindle. Book excerpt: A practical tool on radar systems that will be of major help to technicians, student engineers and engineers working in industry and in radar research and development. The many users of radar as well as systems engineers and designers will also find it highly useful. Also of interest to pilots and flight engineers and military command personnel and military contractors. ""This introduction to the field of radar is intended for actual users of radar. It focuses on the history, main principles, functions, modes, properties and specific nature of modern airborne radar. The book examines radar's role within the system when carrying out is assigned missions, showing the possibilities of radar as well as its limitations. Finally, given the changing operational requirements and the potential opened up by modern technological developments, a concluding section describes how radar may evolve in the future. The authors review the current state of the main types of airborne and spaceborne radar systems, designed for specific missions as well as for the global environment of their host aircraft or satellites. They include numerous examples of the parameters of these radars. The emphasis in the book is not only on a particular radar technique, but equally on the main radar functions and missions. Even if a wide range of techniques are described in this book, the focus is on those which are connected to practical applications.
