The Birth of Radar

摘要

In the second part of 'The Birth of Radar', Brian Kendal continues the story of the development of British radar prior to the outbreak of WWII. When the members of the Tizard Committee - the Committee for the Scientific Survey of Air Defence - visited Orford Ness on 15 June 1935, they had been impressed by the display of ionospheric echoes. However, Watson Watt had decided to stay a further day and the following morning they received a strong aircraft return at 17 miles range. This turned out to be a Scapa Flying boat from the Felixtowe Air Station.
