What type of RADAR is used for air traffic control?

Air Surveillance RADAR is specifically designed for monitoring and controlling aircraft in the airspace. It provides critical information to air traffic controllers, allowing them to track the altitude, speed, and flight path of multiple aircraft simultaneously. This type of RADAR operates by sending out radar waves that reflect off of aircraft and return to the system, allowing for accurate detection and positioning.

Other types of RADAR serve different functions. Ground-based RADAR is primarily used for monitoring ground activities and may not provide the necessary tracking capabilities for high-altitude aircraft. Weather RADAR is focused on detecting and mapping precipitation and atmospheric phenomena, which is not applicable for air traffic control purposes. Marine RADAR, meanwhile, is used for ship navigation and monitoring marine environments, making it unsuitable for air traffic management. Thus, Air Surveillance RADAR is crucial for ensuring the safety and efficiency of air travel.
