Information on Air Traffic Control Radar

Airport radar shows air traffic controllers information on aircraft in controlled air space, and possibly surrounding uncontrolled airspace. Air traffic control radar (ATC radar) systems include:

  • Primary radar, which uses signals scattered off the bodies of aircraft to obtain information on their location and altitude. Primary radar is normally available only close to major airports.
  • Secondary radar, or secondary surveillance radar, which relies on interrogation of transponders carried by aircraft. Secondary radar provides most of the radar coverage available to an air traffic controller, and has a much longer range than primary radar.
