Phased array antennas can be electronically steered and do not have moving parts, making them an efficient and cost-effective solution for today's complex radar and communications systems. This newly revised edition of the Artech House classic, Phased Array Antenna Handbook, offers the most up-to-date and broadest view of array antennas and systems. Professionals find complete design details that allow them to build and evaluate an array system with speed and confidence. The second edition offers a wealth of critical new material, including a detailed treatment of antenna system noise, sections on antenna pattern synthesis, cutting-edge developments in subarray technology, and in-depth information on array architecture and components.

This text is intended for use by engineers and researchers working in phased array theory and technology. It also contains practical design data for antenna designers, radar and communications engineers and array designers and researchers, and should be suitable for use on university courses on antenna rays. This reference provides complete design details enabling systems engineers to size an array system with the minimum of additional information, and includes enough detailed description of analytic methods to enable researchers to assess the state of electromagnetics applicable to this technology. In-depth descriptions include patttern optimization, elements and architecture for arrays and gain, directivity and various effeciencies for generalized arrays.

Scanning arrays present the radar or communications engineer with the ultimate in antenna flexibility. They also present a multitude of new opportunities and new challenges that need to be addressed. In order to describe the needs for scanned array development, this book begins with a brief discussion of the history that led to present array antennas. This text is a compact but comprehensive treatment of the scanned array, from the underlying basis for array pattern behavior to the engineering choices leading to successful design. The book describes the scanned array in terms of radiation from apertures and wire antennas and introduces the effects resulting directly from scanning, including beam broadening, impedance mismatch and gain reduction and pattern squint and those effects of array periodicity including grating and quantization lobes and array blindness. The text also presents the engineering tools for improving pattern control and array efficiency including lattice selection, subarrray technology and pattern synthesis. Equations and figurers quantify the phenomena being described and provide the reader with the tools to tradeoff various performance features. The discussions proceed beyond the introductory material and to the state of the art in modern array design. Contents: Basic Principles and Applications of Array Antennas / Element Coupling Effects in Array Antennas / Array Pattern Synthesis / Subarray Techniques for Limited Field of View and Wide Band Applications

The third edition of an Artech House classic, Phased Array Antenna Handbook, provides new material on array and multibeam antennas and systems, including new methods, devices and machine learning techniques. The authors cover the antenna system design, pattern synthesis, array architecture and components and current developments in subarray technology. Researchers and communication engineers will find the numerous equations and illustrations particularly helpful to evaluate antenna parameters, such as gain, sidelobe levels and noise.
