THREE STEPS TO VICTORY: A PERSONAL ACCOUNT BY RADAR'S GREATEST PIONEER

Watson-Watt recounts the race against time to ring Britain with a radar defense before Hitler invaded.

His ‘three steps’ were ‘Huff Duff’, the instantaneous visual radio direction-finder which was as important to the Battle of the Atlantic as was his second step, Radar which revolutionized the art of war in the air, at sea and on the ground and then proceeded to revolutionize the art of navigation in peace time. The third step was Operational Research which brought the scientist into the planning as well as into the analysis of day to day operations of war.

ABOUT THE AUTHOR 

Sir Robert Alexander Watson Watt KCB FRS FRAeS (13 April 1892 – 5 December 1973) was a British pioneer of radio direction finding and radar technology.

Watt began his career in radio physics with a job at the Met Office, where he began looking for accurate ways to track thunderstorms using the radio signals given off by lightning. This led to the 1920s development of a system later known as high-frequency direction finding (HFDF or "huff-duff"). Although well publicized at the time, the system's enormous military potential was not developed until the late 1930s. Huff-duff allowed operators to determine the location of an enemy radio in seconds and it became a major part of the network of systems that helped defeat the threat of German U-boats during World War II. It is estimated that huff-duff was used in about a quarter of all attacks on U-boats.

In 1935 Watt was asked to comment on reports of a German death ray based on radio. Watt and his assistant Arnold Frederic Wilkins quickly determined it was not possible, but Wilkins suggested using radio signals to locate aircraft at long distances. This led to a February 1935 demonstration where signals from a BBC short-wave transmitter were bounced off a Handley Page Heyford aircraft. Watt led the development of a practical version of this device, which entered service in 1938 under the code name Chain Home. This system provided the vital advance information that helped the Royal Air Force win the Battle of Britain.

After the success of his invention, Watson Watt was sent to the US in 1941 to advise on air defense after Japan's attack on Pearl Harbor. He returned and continued to lead radar development for the War Office and Ministry of Supply. He was elected a Fellow of the Royal Society in 1941, was given a knighthood in 1942 and was awarded the US Medal for Merit in 1946.
