AN/FPS-37 was a two-channel (one channel always in stand-by) fixed radar operating in L-Band for air surveillance and air traffic control. It used an antenna with an antenna gain of 36&nbesp;dBi with either linear or circular polarization.

The electronics of the AN/FPS-37 are similar to the AN/FPS-8 except for the antenna and the dual-channel design. It also has a more effective MTI system and remote control capability.

AN/FPS-37 radar was added to the Air Defense Command network site in Key West (Florida) in 1962 during the Cuban missile crisis, where it formed an important reconnaissance role in the Cold War.
