Dowding System
다우딩 체계
The Dowding System was a wide-area air-defence command network built by RAF Fighter Command shortly before the Second World War. By linking Chain Home radar, the Royal Observer Corps, filter and operations rooms, and dedicated telephone lines, it built a shared picture of British airspace and directed fighters to interceptions, helping Fighter Command use its limited force effectively during the Battle of Britain in 1940.

Structure and operation
The system’s central principle was to collect information centrally and distribute it through a hierarchy. Reports from coastal Chain Home radar stations and the Royal Observer Corps were combined in the Filter Room at Fighter Command Headquarters at Bentley Priory, where operators constructed a plot of the battle. Information was passed to Group and Sector headquarters, whose operations rooms directed fighters by radio. Because radar alone had difficulty tracking low-flying aircraft inland, the combination of observers with command and communications was essential.
Historical significance
The system combined early warning with centralised information processing to allocate fighter sorties by time and place. Its effectiveness therefore lay not in radar as an isolated technology, but in an organisational design that connected detection, identification, reporting, and command.
