Available in PDF, EPUB and Kindle. Book excerpt: Monopulse radars are often used by the U.S. Navy Department to track airborne targets such as missiles attacking ships. In order to effectively make use of the target position data provided by the radar, an estimate of the radar output accuracy must be known. This report describes portions of research performed at Naval Surface Warfare Center, Dahlgren Division (NSWCDD) to develop statistical models of monopulse ratio behavior to improve accuracy analysis of the monopulse radar. The products of this work include a formula for the distribution of the real valued part of the radar signal. Also developed were two tools to compare this distribution with a normal distribution. With these formulas, we showed that, given certain assumptions, this distribution can be approximated by a normal distribution. Finally, this work showed the validity of certain pre-existing formulas developed at NSWCDD. These results are useful in developing algorithms for assessing the accuracy of target location estimates by monopulse radars.

Available in PDF, EPUB and Kindle. Book excerpt: It has been shown that unless there is only a single on-axis target, the angle estimator (monopulse ratio) at the output of a monopulse radar is biased. No matter how large the signal-to-noise ratio, the variance of the estimate is unbounded. A measure of the spread of the probability density function has been introduced and a procedure developed to calculate the spread from the exact closed form expression for the probability density function of the monopulse ratio. The bias is also available by numerically calculating the mean of the probability density function. (Author).
Download or read book Monopulse Radar Theory and Practice Second Edition written by Samuel M. Sherman and published by Artech House. This book was released on 2011 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monopulse is a type of radar that sends additional information in the signal in order to avoid problems caused by rapid changes in signal strength. Monopulse is resistant to jamming which is one of the main reasons it is used in most radar systems today. This updated and expanded edition of an Artech House classic offers you a current and comprehensive treatment of monopulse radar principles, techniques, and applications. The Second Edition features two brand new chapters, covering monopulse countermeasures and counter-countermeasures and monopulse for airborne radar and homing seekers. This essential volume categorizes and describes the various forms of monopulse radar, and analyzes their capabilities and limitations. The book also devotes considerable space to monopulse circuits and hardware components, explaining their functions and performance. This practical resource features numerous photographs and illustrations drawn from actual radar systems and components. This book serves as a valuable reference for both experienced radar engineers and those new to the field.

This book was released on 1966 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is derived a probability density function (p. d. f.) of an amplitude type monopulse radar system output signal. It is supposed that the receivers input signals consist of an hormonic oscillation with unknown initial phase and of additive gaussian noises, the absolute cross-correlation coefficient value of which is supposed to be known. The p. d. f. of the output amplitudes is given by the formula (10). A method of numerical calculation of the quotient (formula (22)), as well as the logarithmic and sum-difference statistics, using an electronic computational machine, is considered. (Author).

Download or read book An Application of the Theory of Games to Radar Reception Problems written by Nils J. Nilsson and published by . This book was released on 1958 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of radar reception in the presence of jamming is treated by an application of the theory of games. The game formulation is as follows: assume the radar receiver employs a matched filter, matched to the radar echo signal, and let the choice of band-limited power spectral distributions for both the radar signal and the jamming noise constitute the respective strategy decisions for the radar designer and the jammer. Games with strategies of this type are known as function-space games. For each opponent, optimum spectral strategies are specified when the payoff function is the receiver output signal-to-noise ratio or the mean squared time error in target location. A new expression for this output signal-to-noise ratio is used which reduces to the familiar 2E/No for the case of constant density noise jamming. When the output S/N ratio is the game payoff function, the optimum spectra are shown to be constant density band-limited spectra for both the radar signal and the jamming noise. The game theoretically optimum linear receiver is a matched filter receiver. When the time error is used as a payoff function, the set of spectra from which the radar designer may choose is limited in a certain way so that the resulting game may be more easily solved. However, a special trick must be used to solve it. Optimum spectra for this game are other than simple constant density spectra.
