ARSR-1, -2
The ARSR-1 was an early, operating in L-Band Air Route Surveillance Radar introduced in 1958. It was the first civil long-range radar (LRR) system designed primarily to provide a display of aircraft locations over large areas. 29 sites ARSR-1 were installed from 1957 through 1964. 17 sites ARSR-2 since 1960. Both radars use crossed-field amplifiers (amplitrons) as their final output stage. The ARSR-2 got a number of filters to reduce parasitic emissions of unwanted frequencies.
The radars were replaced by Westinghouses ARSR-3, later by ARSR-4.
