What does RADAR provide information on regarding objects in the airspace?

RADAR (Radio Detection and Ranging) is a technology that uses radio waves to detect and determine the distance, speed, and direction of objects in the airspace. The key information that RADAR provides includes range, which indicates how far away an object is from the RADAR system; azimuth, which denotes the angle of the object relative to a reference direction (usually true north), and elevation, which describes the height of the object in the vertical axis.

By providing range and azimuth information, RADAR allows air traffic controllers to track the lateral position of aircraft, while elevation data helps in understanding their vertical positioning within the airspace. This comprehensive set of data is crucial for managing air traffic safely and efficiently, enabling controllers to make informed decisions based on the current positions and movements of aircraft.
