Description
Focusing mainly on the engineering aspects of communications electronic warfare (EW) systems, this thoroughly updated and revised edition of a popular Artech House book offers you a current and complete introduction to the subject. The second edition adds a wealth of new material, including expanded treatments of two critical areas - RF noise and the effects of signal fading. Moreover, now you find a complete chapter on the important topic of jamming performance over fading channels. Supported with over 700 equations, this authoritative resource details the components, systems, and operations of electronic warfare systems dedicated to protecting and attacking military communications networks. You are provided with a complete understanding of how modern direction finders for communication signals work, along with their limitations. The book also helps you acquire a working knowledge of hyperbolic emitter location technologies, and shows you how to measure performance, defining the basic operations necessary for communication EW systems. You are provided with a technique for geolocation of low probability of intercept/anti-jam targets. Use this book to identify state-of-the-art EW technology, understand basic EW processes, and gain insight into the future direction of these systems.
