ARSR-3 and 3D search radar were used by the FAA in the Joint Surveillance System (JSS). The radar operated in the L-band at 1250 to 1350 MHz and detected targets at distances beyond 210 nautical miles; 390 kilometres (240 mi). The D model had height-finder capability. Westinghouse also built ARSR-4 3-D air surveillance radar in the 1990s for ...
Secondary surveillance radar antenna (flat rectangle, top) mounted on an ASR-9 primary airport surveillance radar antenna (curved rectangle, bottom).. The need to be able to identify aircraft more easily and reliably led to another wartime radar development, the Identification Friend or Foe (IFF) system, which had been created as a means of positively identifying friendly aircraft from unknowns.
The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next-generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016.
The former J-31 San Pedro JSS ARSR-1 radar site, California USAF Battle Control System operators monitor the skies from the floor of the program's Eastern Air Defense Sector location. The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America.
