The AN/FPS-24 Radar was a long range early warning radar used by the United States Air Force Air Defense Command. It used a two-frequency signal in order to avoid fluctuation loss, which causes signals on single-frequency radars to fade in and out as the target moves. Reducing this effect results in a much steadier signal.
General Electric was the primary contractor for the design, which operated in the very high frequency (VHF) at 214 to 236 MHz.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/FPS-24" designation represents the 24th design of an Army-Navy electronic device for fixed ground search radar. The JETDS system also now is used to name all Department of Defense electronic systems.
