ATM - DASRRaytheon has been helping to modernize FAA and Department of Defense aviation surveillance capabilities through its Digital Airport Surveillance Radar (DASR) program since 1996. Up to 213 systems with outdated equipment will be replaced with a next generation, solid-state terminal area ATC radar system for military and civilian use in phases that run through 2016.  

DASR replaces outdated analog air traffic control systems with digital technology. The DASR ASR-11 is the first fully digital, solid-state radar to be implemented in the U.S. National Airspace System (NAS). So far the radars have been deployed to more than 130 sites throughout the world.

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. It is designed for unattended operation using redundant subsystems with built-in test equipment and can be fully controlled and monitored from multiple locations.

Analog radars are steadily being replaced as part of the NAS Modernization Program, which involves upgrading legacy air traffic control 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.

With the program about half way through, DASR systems are being installed at locations across the USA and at US military bases around the World. One DASR system has already been installed at Baghdad Airport.
