Radar, how it all began

This book offers an unusually close insight into Britain's efforts in the field of radio location (the term 'radar' was not used until the end of the War) in the 1930s. Metropolitan Vickers was responsible for providing parts for the first British system, the Chain Home, which went into operation in September 1938 and soon afterwards played a crucial role in Britain's defence. The author explains subsequent developments, including the production of the Friend-Foe Indicator, which enabled Britain's coastal defences to distinguish between friendly and enemy aircraft, and the improvements to radar which transformed it from a defence weapon to a means of attacking the enemy. He also outlines its role in helping the Royal Navy to defeat the U-boats and shows how it was used in 'jamming' the German radar at the end of the War during the allied bombing raids on German cities and at the time of the D-Day landings.
