The AN/SPY-1 is the electronically scanned fixed-array radar for the US Navy's Aegis fleet air defence system. It operates in the E/F-Band, and the output is in several megawatts. The transmitter serves several parallel channels simultaneously.
The four fixed and phase-scanned arrays of AN/SPY-1 send out beams of electromagnetic energy in all directions simultaneously, continuously providing a search and tracking capability for hundreds of target at the same time. Each array has 4,100 discrete elements, and measures 3.65·3.65 m. These elements are controlled by AN/UYK-7 digital computers to produce and steer multiple radar beams for target search, detection and tracking. The SPY-1 also tracks the ship's own missiles fired against hostile targets. In addition to search and track, it provides midcourse guidance to the Standard missile (SM-2).
The Aegis system has been fully operational since 1983 and advanced versions of the radar have also been developed.
