  2. Radar beacon - Wikipedia

    en.wikipedia.org/wiki/Radar_beacon

    Principle. When a traditional RACON receives a radar pulse, it responds with a signal which on a radar screen takes the form of a short line of dashes and dots forming a Morse character radiating away from the location of the beacon. Typically, the Morse character starts with a dash – a long, continuous signal.

  3. Air traffic control radar beacon system - Wikipedia

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    The air traffic control radar beacon system (ATCRBS) is a system used in air traffic control (ATC) to enhance surveillance radar monitoring and separation of air traffic. It consists of a rotating ground antenna and transponders in aircraft.

  4. Secondary surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Secondary_surveillance_radar

    Secondary surveillance radar (SSR) is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with a radar transponder, that reply to each interrogation signal by transmitting encoded data such ...

  5. Over-the-horizon radar - Wikipedia

    en.wikipedia.org/wiki/Over-the-horizon_radar

    Over-the-horizon radar (OTH), sometimes called beyond the horizon radar (BTH), is a type of radar system with the ability to detect targets at very long ranges, typically hundreds to thousands of kilometres, beyond the radar horizon, which is the distance limit for ordinary radar.

  6. Tactical air navigation system - Wikipedia

    en.wikipedia.org/wiki/Tactical_air_navigation_system

    A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system used by military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne station. It is from an end-user perspective a more accurate version of the VOR / DME system that provides bearing and ...

  7. Air Route Surveillance Radar - Wikipedia

    en.wikipedia.org/wiki/Air_Route_Surveillance_Radar

    Range. 290 miles. The Air Route Surveillance Radar is a long-range radar system. It is used by the United States Air Force and the Federal Aviation Administration to control airspace within and around the borders of the United States.

  8. Distance measuring equipment - Wikipedia

    en.wikipedia.org/wiki/Distance_measuring_equipment

    DME is similar in principle to secondary radar ranging function, except the roles of the equipment in the aircraft and on the ground are reversed. DME was a post-war development based on the identification friend or foe (IFF) systems of World War II. To maintain compatibility, DME is functionally identical to the distance measuring component of ...

  9. Identification friend or foe - Wikipedia

    en.wikipedia.org/wiki/Identification_friend_or_foe

    Identification, friend or foe ( IFF) is a combat identification system designed for command and control. It uses a transponder that listens for an interrogation signal and then sends a response that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. [1]

  10. Primary radar - Wikipedia

    en.wikipedia.org/wiki/Primary_radar

    Principle of primary radar. A primary radar or primary surveillance radar (PSR) is a conventional radar sensor that illuminates a large portion of space with an electromagnetic wave and receives back the reflected waves from targets within that space.

  11. Radio beacon - Wikipedia

    en.wikipedia.org/wiki/Radio_beacon

    In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. But instead of employing visible light , radio beacons transmit electromagnetic radiation in the radio wave band .
