Keller FAA Radar Site
Keller FAA Radar Site (1960s-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LRR) site first established in the 1960s near Keller, Tarrant County, Texas. 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 a SAGE System ID of Z-231, and an FAA ID of FTW. Active FAA Radar Site. Also known as Fort Worth FAA Radar Site.
This site became an FAA radar site in the 1960s, 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 should have been equipped with a Common Digitizer CD-2.
The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Keller 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 Keller 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 Fort Worth ARTCC (ZFW) and adjacent ARTCCs. Other federal agencies have access to the data under the Homeland Security umbrella.
