Radar technology in ITT

With the introduction in the late 1980s and 1990s of such technologies as VLSI, GaAs monolithic circuits, integrated electrooptics, coherent fiber optics, high-power solid-state millimeter-wave sources, and specialized materials, the performance, packaging, and cost of radar systems will undergo radical changes. It is noted by way of example that low-cost GaAs monolithic transmitter/receivers (employing integrated optics technology) coherently fed by way of optical fiber could provide economical phased arrays with many more elements than present antennas. Using optical or high-speed VLSI processors (probably using three-dimensional structures) providing 10 to the 12th or more operations per second, radar systems could be developed with orders of magnitude improvement in performance.
