TheAN/CPS-6 was anS-band medium-range search/height finder radar used by theUnited States Air ForceAir Defense Command. The radar was developed during the later stages ofWorld War II by theMIT Radiation Laboratory with the first units produced byGeneral Electric in mid-1945.
In accordance with theJoint Electronics Type Designation System (JETDS), the "AN/CPS-6" designation represents the 6th design of an Army-Navy air transportable electronic device for search radar equipment. The JETDS system also now is used to name allDepartment of Defense electronic systems.[1][2]
Subsequent development of theAN/CPS-6A andAN/CPS-6B models saw them produced at a plant inSyracuse, New York. The radar set consisted of two antennae, with one slanted at a 45-degree angle providing the height-finder capability. Designed to detect fighter aircraft at a range of 100 miles (160 km) and a height of up to 16,000 feet (4,900 m), the radar utilized five transmitters operating atS-band frequencies ranging between 2.700–3.019 GHz (111.0–99.3 mm). It required twenty-five people to operate the radar.
In 1949, an AN/CPS-6 radar was installed as part of theLashup Radar Network atTwin Lights,New Jersey, proving capable of detecting targets at ranges of 84 miles (135 km). The first units of the follow-on AN/CPS-6B, ready for installation by mid-1950, saw fourteen of these assigned within the first permanentLashup network.
A component designed to improve the radar's range was added in 1954. Tests showed the 6B-model had a range of 165 miles (266 km) with an altitude limit of 45,000 feet (14,000 m). A single radar unit with its ancillary electronic equipment required eighty-five freight cars for transport. The Air Force phased out the 6B-model between mid-1957 and mid-1959.
Another radar, developed from the CPS-6, was theAN/FPS-10. It was essentially a stripped-down version of the AN/CPS-6B.[3] Thirteen of these units served within the first permanent Lashup network.
