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.
