Timed Arrays

Download or read book Timed Arrays written by Randy L. Haupt and published by John Wiley & Sons. This book was released on 2015-04-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces timed arrays and design approaches to meet the newhigh performance standards The author concentrates on any aspect of an antenna array thatmust be viewed from a time perspective. The first chapters brieflyintroduce antenna arrays and explain the difference between phasedand timed arrays. Since timed arrays are designed for realistictime-varying signals and scenarios, the book also reviews widebandsignals, baseband and passband RF signals, polarization and signalbandwidth. Other topics covered include time domain, mutualcoupling, wideband elements, and dispersion. The author alsopresents a number of analog and digital beamforming networks forcreating and manipulating beams. The book concludes with anoverview of the methods to integrate time delay into the arraydesign and of several other adaptive arrays that prove useful inmany different systems. Examines RF signal concepts such as polarization and signalbandwidth and their applications to timed antenna arrays Covers arrays of point source, elements in timed antennaarrays, active electronically scanned array technology, and timedelay in corporate fed arrays Includes complete design examples for placing time delay inarrays Timed Arrays: Wideband and Time Varying Antenna Arrays iswritten for practicing engineers and scientists in wirelesscommunication, radar, and remote sensing as well as graduatestudents and professors interested in advanced antenna topics.
