Texarkana FAA Radar Site
Texarkana FAA Radar Site (1968-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LRR) site first established in 1968 near Texarkana, Miller County, Arkansas. 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-091, and an FAA ID of TXK. Active FAA Radar Site.
This site became an FAA radar site in 1968, furnishing radar track data to the FAA ARTCCs and to USAF Direction Centers. This site was first located on the former Texarkana Air Force Station but was relocated to the present location. The initial FAA FPS-67 search radar on the new site remained in operation until it was modified to become a CARSR radar with a 1561 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 FPS-67 search radar and a CD-2 Common Digitizer. The Texarkana CD-2 was scheduled to receive an upgrade kit to implement three level weather data processing in July 1992.
The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Texarkana 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 Texarkana 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.
