648 pages; $95.95
Major changes in antenna applications have occurred since this book was first published in 1981. This second edition has been appropriately updated to encompass these new applications, which have developed mainly in wireless communications. The book covers antennas from three perspectives: fundamentals, techniques and design.
Chapter 1 assumes the reader has had little exposure to antenna theory and presents antenna fundamentals, including Maxwell’s equations and an explanation of antenna radiation. Chapter 2 examines simple radiating systems such as dipoles, and Chapter 3 expands this analysis to antenna arrays. The relationship between current distribution and its spatial radiation characteristics is explained using elementary mathematics. Chapter 4 covers line source antennas.
The next section provides details on commonly used antennas with an emphasis on operating principles and design guidelines. Chapter 5 surveys the resonant antenna elements, including dipoles, yagis and microstrip patches. Chapter 6 discusses broadband antennas such as helix, spiral and log-periodic. Chapter 7 examines aperture antennas.
The synthesis of arrays and continuous antennas is presented in Chapter 8 for shaped main-beam or low side lobe applications. The use of antennas as devices in systems is described in Chapter 9 along with antenna measurements.
Chapters 10 through 12 introduce computational electromagnetic techniques for evaluating simple antenna elements as well as large complex antenna systems. The appendix lists key computational and visualization antenna software packages available on the World Wide Web. Information on the radio spectrum, materials and important mathematical relations is also included.
This book is a useful resource for both introductory and advanced-level course work that also can be used by practicing engineers as a general reference text. The authors have presented a very complex subject in an easily understood fashion.

Millimeter-wave and Infrared Multisensor Design and Signal Processing
Lawrence A. Klein
Artech House Inc.
428 pages; $99, £79
Multisensor architectures may be designed and produced cost-effectively to enhance the detection of military and other observable targets under a diverse set of operating conditions such as high clutter, inclement weather and military countermeasures. This book focuses on passive and active sensor operation, atmospheric and weather effects, detection theory, clutter decorrelation, measures of optical image quality, signal processing algorithms and data fusion.
Chapter 1 explains the need for sensors in modern weapon systems. Chapter 2 discusses the benefits of a multisensor suite, attributes and selection of active or passive sensors, selection of the receiver frequency spectrum, techniques to combine sensor data and properties of critical millimeter-wave (MMW) and infrared (IR) sensor hardware. Chapter 3 explains the effects of the atmosphere and obscurants on MMW and IR sensors. Chapter 4 describes MMW radar sensors’ composition, operation and problems.
The design and operation of a frequency-modulated, continuous-wave radar are covered in Chapter 5. Chapter 6 describes passive MMW sensors (sensors that receive energy that is emitted or transmitted from other sources). Radiative transfer theory is discussed to provide an understanding of the contributions of the atmosphere and ground-based materials to the passive signature of observed objects. Chapter 7 discusses the design of imaging and nonimaging passive IR sensors and the figures of merit commonly used to characterize their performance.
The military applications of laser radars and methods to calculate their signal-to-noise ratio and detection probability performance are described in Chapter 8. Chapter 9 describes the windows and domes that protect the enclosed focal plane structure of IR sensors or the antenna on MMW sensors from environmental effects. The final chapter details MMW/IR dual-sensor design.
