AN/FPS-124

The AN/FPS-124 is a gap filler radar for the North Warning System. The radar is a high-reliability, unattended and easily maintained short-range radar designed to operate in conjunction with the AN/FPS-117 long-range surveillance radars in the upgraded North Warning System. The radars can detect and track small radar cross section, low flying targets, and are to be particularly effective in detecting cruise missile penetration of US and Canadian airspace.

FPS-124 uses a cylindrical phased-array antenne operating in L-Band that is approximately 12 ft (3.66 m) tall with a diameter of 5 ft (1.25 m). The electronics for the transmitter/controller are located inside the cylindrical assembly. It is cooled by 11 fans, which are the only moving parts in the system.

A total of 39 units have been produced.
