ARSR-1 Long-Range Search Radar Set - A long-range ground search radar set built by Raytheon for the Federal Aviation Administration (FAA). First deployed in 1958.
ARSR-1 Search Radar
The ARSR-1 was an long-range L-band (1215- 1400 MHz) air-route-surveillance radar built by Raytheon for the FAA. Twenty nine ARSR-1s were deployed by the FAA starting in 1958. The ARSR-1 was used as a surveillance system to detect azimuth and range of en route aircraft operating between FAA terminal areas.The ARSR-1 used a conventional magnetron feeding 400 kW peak power into an amplitron to provide an additional 10 dB gain.
ARSR-1E Search Radar
By the mid-1990s the FAA had updated the ARSR-1 to the ARSR-1E Model and was operating it at 29 JSS and FAA Sites. The ARSR-1E was based on the 1960s vintage ARSR-1 radar that was updated through a Service Life Extension Program (SLEP). It was still basically a long-range radar system with a maximum detection range of about 200 nautical miles (nmi). It also provided weather intensity data.
The ARSR-1E could also be interfaced to a collocated Common Digitizer Model 1/2 (CD-1/CD-2) or other digital processors which provided digitized output.
By 2015 all of the operating ARSR-1Es had been further transformed into Common Air-Route-Surveillance (CARSR) radars with additional solid state components that would extend the supportable life of the set.
