ASR-B1

The ASR-B1 was operating in S band vacuum tube-based, stationary 2D- airport surveillance radar. The radar was in service from 1963 to 1982, at the beginning as ASR-B without secondary radar, later (as shown in the picture) with a beacon-shaped monopulse antenna.

From the early 1980s it was replaced by the ASR 910.

A version of the ASR-B1 for target assignment for antiaircraft missile complexes was called ASR-P “Paula” (from “Primary radar” to distinguish the data from ASR-SSR). One set stood as a front-line surveillance radar on the island of Helgoland. This equipment remained in inventory until 1988, when it was shut down for cost reasons. An ASR 910 was then used on Helgoland until March 2003.
