Description
Combining and updating the author's two definitive volumes on electronic intelligence (ELINT), this is your indispensable reference on radar's role in ELINT. Starting with the basic theory of range equations and probability of intercept, the book examines ELINT systems characteristics, performance issues, and essential functions. It gives you new insight into PRI and intrapulse analysis so you can obtain better results and more data for identifying signals. Supported with over 240 illustrations and more nearly 300 equations, this in-depth resource helps you more fully understand the benefits and limitations of ELINT information that is so crucial in electronic warfare You learn how to draw more cohesive conclusions about radar's capabilities that are implied by observed signal parameters. Moreover, the book teaches you how to recognize the strengths and weaknesses of different receiver configurations and master the challenges of LPI radar signals.
