RADAR Patent Awarded

In 1935, Scottish physicist, Sir Robert Watson-Watt was granted a patent for the RADAR (RAdio Detection And Ranging). He became head of the radio section of the National Physical Laboratory (1935), where his work on locating aircraft was an outgrowth of his earlier work on radio-wave detection of thunderstorms to benefit airmen. He realized the principle could also be used to track enemy aircraft for air defense. On 26 Feb 1935, he gave a demonstration to Air Ministry officials showing the reflected signal when a RAF bomber flew through the beam of a BBC short-wave transmitter. His work led to the development of radar which played a vital role in the defence of Britain against German air raids in 1940.
