What can a radar detect?

Radar (radio detection and ranging) is a detection system that uses radio waves to determine the distance (ranging), angle, or relative velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain .

How far away can radar detect things?

This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km) . Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
