A major expansion and revision of the 1985 edition. Describes in detail the fundamental principles and latest techniques that resist unintentional interference, prevent jamming and detection by an opponent, and thwart unauthorized extraction of information from a transmitted waveform. Would-be intruders are becoming increasingly sophisticated; to hold their own, design engineers must know the physical and mathematical principles involved and how to perform a thorough systems-level security analysis.
