This chapter serves as an introduction to Part I of Volume 2 of the book, on the subjects of Waveform Diversity and Cognitive Radar. These are relatively recent concepts, and twenty years ago the terms would hardly have been recognized. Now, though, they can both be regarded as mainstream subjects in radar research, with entire sessions at radar conferences devoted to them.
