- SMR in an airport context stands for Surface Movement Radar. It is a radar system used primarily to monitor and control the movement of aircraft and ground vehicles at airports. SMR helps air traffic controllers track the positions and movements of aircraft, vehicles and other objects on runways, taxiways and aprons. This radar system helps maintain safe and efficient ground operations by providing real-time situational awareness to air traffic control personnel.
- The full form of SMR in airport terminology is surface motion radar.
This radar technology is essential for air traffic management on the ground, ensuring safe and orderly movement of aircraft and vehicles to prevent collisions and maintain operational efficiency.
- Secondary surveillance radar (SSR) works in conjunction with primary radar systems to provide additional information about aircraft. SSR relies on transponders installed in aircraft, which respond to radar signals by transmitting identification, altitude and other flight data to the radar station.
This allows air traffic controllers to identify and track aircraft more precisely, distinguish between different planes and verify their positions and flight information.
- ASR in an airport context means airport surveillance radar. ASR is a primary radar system used to detect and track aircraft in the airspace around an airport. It provides air traffic controllers with essential information about aircraft positions, speeds and altitudes, helping them manage air traffic, clearances issuing takeoffs and landings and maintain safe separation between aircraft.
Airport surveillance radar is essential to ensure the safety and efficiency of airport operations, especially during the approach and departure phases of flights.
