How do radar and surveillance systems contribute to monitoring and tracking aircraft movements in air traffic control?

Radar and surveillance systems play a crucial role in monitoring and tracking aircraft movements in air traffic control (ATC). These systems provide controllers with real-time information about aircraft positions, altitudes, speeds, and headings, allowing for effective management of air traffic. Here is an in-depth explanation of how radar and surveillance systems contribute to monitoring and tracking aircraft movements in ATC: 1. Radar Technology: Radar (Radio Detection and Ranging) is a primary surveillance technology used in ATC. It operates by emitting radio waves that bounce off aircraft and other objects in the airspace. By measuring the time it takes for the radio waves to return, the radar system can determine the distance, direction, and altitude of the aircraft. 2. Primary Surveillance Radar (PSR): PSR provides basic information about aircraft positions. It detects the presence of aircraft and provides their range and azimuth. However, it does not provide detailed identification or altitude information. 3. Secondary Surveillance Radar (SSR): SSR is an enhanced radar system that works in conjunction with transponders onboard aircraft. Transponders reply to radar interrogations with additional information, including aircraft identification (Mode A) and altitude (Mod....
