Raytheon radars acquired for US Navy ATC upgrade
Raytheon has announced that the US Navy has purchased two more of its radar systems as part of a continuing effort to replace outdated analogue air traffic control (ATC) systems with digital technology. According to a 23 April 2012 statement, the new radars will be installed at military bases in New River, N.C., and Quantico, Va.
The Digital Airport Surveillance Radar (DASR) ASR-11 is the first fully digital, solid-state radar to be implemented in the US National Airspace System (NAS). The radars have been deployed to more than 130 sites throughout the world, and will eventually be in more than 150 sites total.
The ASR-11 provides primary surveillance radar coverage up to 60 miles and secondary surveillance radar coverage up to 120 miles. It provides the air traffic controller with improved aircraft detection, lower support costs and better weather display. The primary radar is being manufactured in Waterloo, Canada, while the secondary radar will be made in the United States and United Kingdom.
Analogue radars are steadily being replaced as part of the NAS Modernisation Program, which involves upgrading legacy ATC systems with modern digital technology to enable the Navy to keep pace with changing Federal Aviation Administration guidelines and standards for terminal radar approach controls.
The digital radar is also an integral part of Raytheon's recently introduced Mobile Air Traffic Control system, which provides critical air traffic services when existing infrastructure has been damaged or does not exist.
