AN/FPS-49

The AN/FPS-49 was an operating in UHF-Band five-horn monopulse tracking radar for use in the BMEWS program and the satellite-tracking program that deployed in the 1960s. It utilizes a mechanical moved parabolic antenna with a weight of 112 tons and 84 feet in diameter, housed in a 140 feet high radome. The prototype unit operated at Moorestown, New Jersey.

Radar Set AN/FPS-49 aquires and automatically tracks detected space objects, accurating sufficient detailed information so that doubtful targets can be definitely identified and their lounch and impact points computed accurately. The set can be used for either missile tracking or detection. Also, it can substitute for a detection radar in a standard scan mode or be assigned to special flexible scan modes to overcome electromagnetic environmental condition. Intended use for AN/FPS-49 is long range, pulse Doppler, monopulse radar capable of providing target coordinates in azimuth, elevation, range and range rate.

The AN/FPS-49 is similar but not interchangeable with Radar Set AN/FPS-49A, and AN/FPS-92. The AN/FPS-49 radome differs due to environmetal conditions. The AN/FPS-49 is located at site Fylingdales (England), the AN/FPS-49A at site Thule (Greenland), and the AN/FPS-92 at site Clear (Alaska). All five radar sets were replaced by a phased array radar of the “Pave Paws” radar family.
