Indianapolis FAA Radar Site
Indianapolis FAA Radar Site (1962c-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LRR) site established by 1962 in Indianapolis, Marion County, Indiana. The site is used to identify and track military and civilian aircraft movements within a 200-mile radius and to provide air-ground radio communication with those aircraft. Assigned an FAA ID of IND. Active FAA Radar Site. HistoryThis site became an FAA radar site by December 1962, furnishing radar track data to the FAA ARTCCs and to USAF Direction Centers. The initial FAA ARSR-1 search radar remained in operation until it was modified to become a CARSR radar with a 7172 Antenna. A FYQ-47 Common Digitizer was probably placed in service by February 1973 when the USAF/FAA FST-2 to FYQ-47 replacement program was completed. By 1990 the site was equipped with an ARSR-1E search radar and a CD-2A Common Digitizer. The Indianapolis CD-2A was scheduled to receive an upgrade kit to implement three level weather data processing on 19 Oct 1990. CARSR RadarThe nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Indianapolis FAA Radar Site was a part of that program. Legacy FAA radars underwent a Service Life Extension Program (SLEP) that replaced key components in the vintage ARSR-1, ARSR-2, FPS-20, FPS-66 and FPS-67 radars. The CARSR program replaced legacy klystron radar transmitters with a solid-state transmitter as well as renovating the radar receiver and signal processor. The CARSR modification also included common digitizer functionality making a separate common digitizer unnecessary. The Indianapolis FAA Radar Site is now operating with the CARSR radar. The secondary radar at this site is an ATCBI-6 Beacon set. The radar site data is now available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA Indianapolis ARTCC (ZID) and adjacent ARTCCs. Other federal agencies have access to the data under the Homeland Security umbrella.
