1935
- Britain commenced radar research for aircraft detection in 1935. The British government encouraged engineers to proceed rapidly because it was quite concerned about the growing possibility of war. By September 1938 the first British radar system, the Chain Home, had gone into 24-hour operation, and it remained operational throughout the war.

May 31, 2024 · Radar - Detection, Military, Technology: Serious developmental work on radar began in the 1930s, but the basic idea of radar had its origins in the classical experiments on electromagnetic radiation conducted by German physicist Heinrich Hertz during the late 1880s.
May 31, 2024 · Radar - WWII, Detection, Technology: The opening of higher frequencies (those of the microwave region) to radar, with its attendant advantages, came about in late 1939 when the cavity magnetron oscillator was invented by British physicists at the University of Birmingham.
2 days ago · The development of the improved radar by the Allies began in 1940, before the United States entered the war, when Henry Tizard and A. V. Hill won permission to share British secret research with the Americans, including bringing them a cavity magnetron, which generates the needed high-frequency radio waves.
Jun 12, 2024 · The British began using microwave radar in the late 1930s to monitor enemy aircraft, but it was soon learned that radar gave excellent returns from raindrops at certain wavelengths (5 to 10 centimetres).
2 days ago · Electronic countermeasures were employed by the B.1 (designated B.1A) and B.2 from around 1960. A change to low-level tactics was made in the mid-1960s. In the mid-1970s, nine Vulcans were adapted for maritime radar reconnaissance operations, redesignated as B.2 (MRR).

2 days ago · The project that eventually led to the AV-8B's creation started in the early 1970s as a cooperative effort between the United States and United Kingdom, aimed at addressing the operational inadequacies of the first-generation Hawker Siddeley Harrier.
May 25, 2024 · British airfields - 'radar on demand'. Prior to about 1985/86, most ATC operations at LBA were provided on a single combined Tower and Approach frequency (123.75 as it was). 120.3 was retained as the Tower frequency but not hitherto used AFAIK. The radar frequency was 121.05 and the radar was only activated to provide vectors for inbound ...
