Array

The first complete guide to phased array design and theory in more than thirty years destined to become the standard reference in the field well into the twenty-first century The past twenty years have witnessed significant breakthroughs in our understanding of the principles behind phased array antennas and in their design and application. Yet not since R. C. Hansen's 1966 classic, Microwave Scanning Antennas, has there been a comprehensive reference in the field. Phased Array Antennas fills the gap in the professional literature. Phased Array Antennas is geared to the interests of both the practicing design engineer and the antenna array analyst. Written by an internationally recognized expert with more than four decades of experience in the field, it offers detailed coverage of all practical and theoretical aspects of phased arrays from quantization lobes and low sidelobe pattern design and measurement to superdirectivity and HTS antennas and frequency scanners. It also provides in-depth coverage of topics such as finite array Gibbsian models, photonic feeding and time delay, waveguide simulators, and beam orthogonality. A multitude of original curves and tables show particular behaviors derived from hundreds of programs developed by the author over the past twenty years, and numerous computer design algorithms and numerical tips are found throughout the book. Phased Array Antennas is an indispensable tool-of-the-trade for antenna design engineers, radar engineers, PCS engineers, and communications engineers. It also serves as a complete text in phased array design and theory for advanced undergraduate-and graduate-level courses in electronics and communications.

" Once again, Harry Van Trees has written the definitive textbook and research reference." – Norman L. Owsley Office of Naval Research, IPA University of Rhode Island A comprehensive treatment of optimum array processing Array processing plays an important role in many diverse application areas, including radar, sonar, communications, seismology, radio astronomy, tomography, and cellular communications. Optimum Array Processing gives an integrated presentation of classical and statistical array processing. Classical analysis and synthesis techniques for linear and planar arrays are developed. A statistical characterization of space-time random processes is provided. Many different aspects of optimum array processing are covered, including waveform estimation, adaptive beamforming, parameter estimation, and signal detection. Both plane-wave signals and spatially spread signals are studied, and all results are developed in a pedagogically sound manner. This book provides a fundamental understanding of array processing that is ample preparation for research or implementation of actual array processing systems. It provides a comprehensive synthesis of the array processing literature and includes more than 2,000 references. Readers will find an extensive variety of models and criteria for study and comparison, realistic examples and practical applications of optimum algorithms, challenging problems that expand the book’ s material, and detailed derivations of important results. A supplemental Web site is available that contains MATLAB® scripts for most of the figures used in the book so readers can explore diverse scenarios. The book uses results fromParts I and III of Detection, Estimation, and Modulation Theory. These two books have been reprinted in paperback for availability.

Dynamic array - A dynamic array, growable array, resizable array, dynamic table, or array list is a data structure, an array which is automatically expanded to accommodate new objects if filled beyond its current size. It may also automatically deallocate some of its unused space to save memory.

Macrocell array - A macrocell array is an approach to the design and manufacture of ASICs. Essentially, it is a small step up from the otherwise similar gate array, but rather than being a prefabricated array of simple logic gates, the macrocell array is a prefabricated array of higher-level logic functions such as flip-flops, ALU functions, registers, and the like.

Systolic array - By analogy with the regular pumping of blood by the heart, a systolic array is an arrangement of processors in an array (often rectangular) where data flows synchronously across the array between neighbours, usually with different data flowing in different directions.

Collinear antenna array - In telecommunication, a collinear antenna array is an array of dipole antennas mounted in such a manner that every element of each antenna is in an extension, with respect to its long axis, of its counterparts in the other antennas in the array.

Term RAID for purpose the purpose of this article, we will say that any system which employs the basic RAID concepts to recombine physical disk space for purposes of reliability or performance is a RAID system. In 1988, RAID levels 1 through 5 were formally defined by David A. Patterson, Garth A. Gibson and Randy H. Katz in the SIGMOD Conference 1988: pp 109 116. RAID is typically used on server computers, and is usually implemented with identically-sized disk drives. This paper spawned the entire disk array industry. In its original implementations (in which it was an abbreviation for "Redundant array of Inexpensive Disks"), its key advantage was the ability to combine multiple hard drives into one single logical unit. For the purpose of this article, we will say that any system which employs the basic RAID concepts to recombine physical disk space for purposes of reliability or performance is a way to combine multiple low-cost devices using the newest technology. So instead of four different hard drives, the operating system sees only one. Hardware vs. Software RA...
