Die Radar-Story, Teil 2

Radar Radar is indispensable in modern aviation. During the Battle of Britain in World War II, the British knew of impending German attacks even before their bombers appeared in the sky. The first technology for this was only developed in the 1930s. Sir John Turton Randall (March 23, 1905 – June 16, 1984) was an English physicist and biophysicist credited with the radical improvement of the cavity magnetron, a key component of centimeter-wavelength radar, which was one of the keys to the Allied victory in World War II. 80 Years of the Cavity Magnetron The year 2025 marks the 85th anniversary of the development of the cavity magnetron, a small but extremely powerful and robust radiovalve originally used in wartime radar and now the heart of every microwave oven. Originally developed in 1940 at the University of Birmingham by John Randall and Harry Boot and manufactured by GEC in Wembley, UK, the magnetron was used to build the world's first high-performance compact radars for installation on warships, aircraft, and vehicles. These radars helped locate submarines during the Battle of the Atlantic and defend against the German V-1 flying bomb attacks in 1944/45. Absolutely remarkable what was achieved here on the physics level! My book recommendation: Cajus Bekker "Eyes Through Night and Fog."
