This book was released on 1969 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a matrix method for maximizing aerial directive gain while simultaneously placing nulls in the far-field radiation pattern of the array. The technique is applicable to linear aerial arrays of N elements, arbitrarily spaced, and allows the designer to specify the directions of up to (N - 1) independent pattern nulls and/or sidelobes, while providing maximum gain in some prespecified direction. This control is achieved by varying only the amplitude and phase of the element currents. The method can be used even when element factors and interelement mutual coupling is included in the expression for directive gain. (Author).
Book Synopsis Processing for Maximum Signal-to-clutter in AMTI Radars by : William Bernard Goggins
Download or read book Processing for Maximum Signal-to-clutter in AMTI Radars written by William Bernard Goggins and published by . This book was released on 1974 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phased array antennas and doppler signal processors designed to complement each other have been successfully used to maximize the signal-to-clutter (S/C) performance of AMTI radars. The optimum receiving antennas described in this paper allow for nonuniformities created in the ground-clutter doppler spectrum by the transmitting antenna and processing of the received doppler signal; the optimum signal-to-clutter digital processors allow for clutter spectra shaped by the combined effects of the transmitting-receiving antennas. The emphasis has been placed on producing antenna-processor designs that have complementary pass and reject bands. The mathematical techniques used in these designs maximize the ratio between the target signal and the clutter-plus-noise, expressed as a ratio of quadratic forms. The solution for the optimum design, which depends principally on the inversion of a single matrix rather than on any recursive technique, is obtained in closed form.

Book Synopsis Receiving Array Coefficients that Minimize Interference and Noise by : John N. Pierce
Download or read book Receiving Array Coefficients that Minimize Interference and Noise written by John N. Pierce and published by . This book was released on 1970 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A formula is derived for the optimum combining coefficients for an antenna array in order to maximize the signal-to-noise ratio in the presence of external interference and local noise. The parameters necessary for the optimization can be determined from in-place measurements on the array element outputs, or can be calculated from known statistics of the interference. The technique is illustrated by theoretically optimized arrays for single and multiple interfering sources at fixed locations, for distributed sky noise, for randomly located interfering sources, and for interfering sources at fixed but uncertain location. The technique lends optimizing the performance of electronically steerable arrays. (Author).
Book Synopsis Orthogonal Methods for Array Synthesis by : John Sahalos
Download or read book Orthogonal Methods for Array Synthesis written by John Sahalos and published by John Wiley & Sons. This book was released on 2007-01-11 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first time that such a complete systematic analysis of the mathematical and numerical techniques related to the orthogonal methods has been given. With the explosion of the wireless world, greater emphasis than ever before is being placed on the effective design of antennas. Orthogonal Methods for Array Synthesis outlines several procedures of orthogonal methods suitable for antenna array synthesis. The book presents a simple approach to the design of antenna arrays to enable the reader to use the classical Orthogonal Method for synthesis of linear arrays. This theory-based book, which includes rapid, effective solutions to design problems for communications applications and broadcasting, is amply illustrated with real-world examples and case studies. Also included in the book is the ORAMA MS Windows-compatible computer tool, patented by Professor Sahalos and his team. Provides comprehensive coverage of the basic principles of orthogonal methods including an analytical explanation of the orthogonal method (OM) and the orthogonal perturbation method (OP) Gives rapid, cost-effective solutions to antenna design problems for communications applications and broadcasting Illustrates all theory with practical applications gleaned from the author’s extensive experience in the field of orthogonal advanced methods for antennas Providing a complete guide to the theory and applications of the Orthogonal Methods, this book is a must-read for antenna engineers and graduate students of electrical and computer engineering and physics.

Book Synopsis Phased Array Antenna Handbook, Third Edition by : Robert J. Mailloux
Download or read book Phased Array Antenna Handbook, Third Edition written by Robert J. Mailloux and published by Artech House. This book was released on 2017-11-30 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: This completely revised third edition of an Artech House classic, Phased Array Antenna Handbook, Second Edition, offers an up-to-date and comprehensive treatment of array antennas and systems. This edition provides a wealth of new material, including expanded coverage of phased array and multiple beam antennas. New modern machine learning techniques used for analysis are included. Additional material on wideband antennas and wideband coverage in array antennas are incorporated in this book, including new methods, devices, and technologies that have developed since the second edition. A detailed treatment of antenna system noise, sections on antenna pattern synthesis, developments in subarray technology, and in-depth coverage of array architecture and components are additional new features of this book. The book explores design elements that demonstrate how to size an array system with speed and confidence. Moreover, this resource provides expanded coverage of systems aspects of arrays for radar and communications. Supported with numerous equations and illustrations, this practical book helps evaluate basic antenna parameters such as gain, sidelobe levels, and noise. Readers learn how to compute antenna system noise, design subarray geometries for given bandwidth, scan and sidelobe constraints, and choose array illumination tapers for given sidelobe levels.

Download or read book Adaptive Arrays written by Edmond Nicolau and published by Elsevier Publishing Company. This book was released on 1989 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive arrays have many practical applications in engineering. Many research papers and reviews describe various types of adaptive arrays used in radar, sonar, seismic data processing, radionavigation, direction of arrival estimation, detection, and so on. A systematic outline of the field of adaptive arrays is provided in this book, offering a current overview of the large number of original contributions contained in the technical literature. This is the completely revised English version of the original Romanian edition. The 600 or more works consulted have enabled the authors to present topics from the earliest sources up to the latest developments in the field. Although the emphasis is mainly on the practical aspects, also included are design elements, technical and technological considerations, which make the book useful to a wide range of specialists. Besides the conventional adaptive processing techniques, nonconventional approaches are included such as reactively controlled arrays, adaptive arrays with optical processing, arrays used in frequency hopping communications systems, etc. Special attention is paid to recent applications of adaptive arrays, with a complete chapter devoted to superresolution and direction of arrival estimation. The book is self-contained, in that any person with a background in electrical engineering can follow the computations. Simple numerical examples are used throughout to illustrate the topics presented. The work is intended for researchers, designers, practitioners, high school teachers, students and engineers in radiocommunications, radar, electrical engineering, aerospace engineering, and control systems engineering.
