The AN/FPS-20 was a widely used L–Band early warning and ground-controlled interception radar system, developed by Bendix orporation. The radar family started with the AN/FPS-3 in 1950, used a transmitter with two magnetrons.
The production of AN/FPS-20 began in 1956 with a dual-channel liquid-cooled klystron transmitter. Each receiver used the “Dicke Fix”- processing. The antenna was equipped with a polarizer and could work alternating in circular or linear horizontal polarization.
Later updates (including anti-jamming opportunities mostly) led to the designations AN/FPS-64, AN/FPS-65, AN/FPS-66, AN/FPS-67, AN/FPS-91, AN/FPS-93, AN/FPS-100, AN/FPS-113, AN/GPS-4, and AN/FPS-508.
