Target allocation radar TPS-1E
The Target allocation radar TPS-1E (German:Zielzuweisungsradar TPS-1E (ZZR)) is an omnidirectional pulse radar device. It was used from 1958 until 1989 by the Swiss Air Force. It was also used by German army ("Heer") air defence reconnaissance platoons up until the early 1990s. History. TPS-1E was ordered in the late 1950s for the heavy antiaircraft units. Target data were transmitted by telephone or radio to anti-aircraft artillery batteries. In the radar equipped batteries with the Fire control radar Mark VII, the Parallax computer Meta converted the data to local coordinates. In the remaining heavy  antiaircraft radar batteries, data were used in manual targeting. In the middle of 1963 the ZZR was used together with the new Air Defence Operations Center 63 for the same task. After the introduction of fire control unit 75, Skyguard ZZR was incorporated in the new mobile radar units. It was used until the introduction of the TAFLIR systems in 1989.
