Who proposed that enemy aircrafts could be detected by radio waves and is responsible for the development of the radar?
Correct Answer: Sir Robert Watson-Watt
Radar was developed by Scotsman Sir Robert Watson-Watt (1892–1973), who proposed that enemy aircraft could be detected by radio waves.
The first successful radar test took place in 1935. Radar proved crucial during the Battle of Britain in 1940, giving the RAF advance warning of incoming Luftwaffe attacks and playing a vital role in Britain's defence.
