This work provides engineers with the information necessary to integrate the fields of optics and electronics. Using a blend of expertise from industry, academia and government, the text shows the applications of this technology, both for future systems and in the evolution of today's radar. The areas covered include optical integrated circuits, optical control of phased array antennas, and high-speed signal processing. Intended for anyone interested in the future of radar, this text is augmented with 508 equations and 285 illustrations.
