The U.S. Navy has purchased two more radar systems from Raytheon Company as part of a continuing effort to replace outdated analog air traffic control systems with digital technology. 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 U.S. 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.
