Microwave Passive Direction Finding unifies direction finding (DF) theory and brings together into a single source wide-ranging information on the technology of measuring the direction-of-arrival of microwave signals.
Throughout the material, there is authoritative information useful to preparing a detailed technical proposal for new business that has been compiled from many years of defense industry presentations, reports, and systems development.
Diagrams and photographs of state-of-the-art equipment depict the methods discussed, and equations and charts facilitate a “hands-on” approach to calculating system performance.
Microwave Passive Direction Finding also presents rarely published systems concepts, such as digital preprocessing, supercommutation, and wide RF bandwidth signal detection methods.
Specific sections cover evolution and use of monopulse passive DF receiver theory, design of antenna elements for conformal DF coverage, receiver configurations, DF antenna arrays, interferometer DF techniques, computation methods for signal detection, probability of detection, accuracy of DF systems, and signal processing and display methods.
More than any book on this technology, Microwave Passive Direction Finding anticipates the questions that arise in the DF design process.
The chapters are organized to stand alone, making Microwave Passive Direction Finding useful as a text/reference for the practicing engineer.
