Phased Array Antennas
R.C. Hansen
John Wiley & Sons
486 pages; $105
ISBN: 0-471-53076-X

Radars that utilize electronic scanning arrays are commonly used in a range of applications from airport surveillance to missile detection and tracking. This book is a comprehensive treatment of all aspects of phased arrays, updated with the inclusion of design algorithms suitable for computers and numerical tips sprinkled throughout the chapters. The text has been prepared for both design engineers and antenna array analysts.

After a brief introduction, the book offers an explanation of basic array characteristics, covering grating lobes, quantization lobes, bandwidth and directivity. Highly efficient linear aperture and array synthesis techniques are then covered, including sum and difference patterns. Next, the synthesis of planar arrays is presented. Array elements are discussed, including classic dipoles and slots, and TEM horns and patches. Fixed beam and scanning feeds for linear and planar arrays also are covered as well as photonic time delay and feeders.

Methods for calculating mutual impedance and array performance with mutual impedance are described. (Mutual impedance has a significant effect on array performance.) These methods include unit cell, spectral moment, finite impedance matrix and scattering techniques. Next, finite arrays are examined, including recently developed Gibbsian models. An extensive view of superdirective arrays is offered where the implications of high temperature superconductors for antennas is an important feature. Multibeam arrays are described, including one-dimensional and two-dimensional Butler and Rotman lenses. Conformal arrays are also described, and the book concludes with a discussion of array diagnostics, waveguide simulators and array tolerance.

The book contains an abundance of clear diagrams and photographs of various antenna arrays and performance diagrams. The author has kept the laborious mathematical derivations to a minimum, choosing instead to relegate most of that to an extensive list of reference material. The subject matter is presented logically and easily understood.

Radar Technology Encyclopedia
David K. Barton and Sergey A. Leonov
Artech House Inc.
511 pages; $105, £79
ISBN: 0-89006-893-3

This book is a joint effort by leading US and Russian radar experts who have extensive experience in the design, development and test of state-of-the-art radar systems and technology. David Barton is a well-known US radar expert with service in the US Army Signal Corp, RCA and Raytheon. He is the author of a number of radar textbooks. Sergey Leonov is known in both Russia and the West as a bilingual radar expert with experience in the Russian space programs as well as design and test of shipborne and spaceborne radars as research head of the research laboratory in the Moscow Aerospace Institute and Raytheon Canada. He is also the author of several radar texts.

The encyclopedia contains approximately 5000 entries that provide a definition of the depicted term, the standard notation (if applicable), evaluation formulas, relevant block diagrams, performance summaries and a reference to the literature where more detailed information is available. The purpose of the book is to provide, in a single volume, the most up-to-date information available in both the former Soviet Union and the West for researchers and engineers in radar and related fields. It contains an extensive bibliography of sources from both regions, covering practically all of the textbooks in radar and related subjects published after World War II in English and Russian.

The encyclopedia’s format is alphabetical, by top-level subject, with sub-articles given a conventional word order typically used in literature and alphabetically arranged. For the most part, definitions of terms are derived from the IEEE Standard Dictionary of Electrical and Electronics Terms and IEEE Standard Radar Definitions . Specific radar stations and facilities are not listed since even a brief description of the major radars developed throughout the world would require a volume in itself. However, extensive examples of modern radars are provided.

To order this book, contact: Artech House Inc., 685 Canton St., Norwood, MA 02062 (781) 769-9750, ext. 4002; or 46 Gillingham St., London SW1V 1HH, UK +44 (0)171 973 8077.
