WORLD HISTORY

Detailed explanation-1: -Radar could pick up incoming enemy aircraft at a range of 80 miles and played a crucial role in the Battle of Britain by giving air defences early warning of German attacks.

Detailed explanation-2: -One of the greatest radar pioneers was Sir Robert Watson-Watt, who developed the first practical radar system that helped defend the British in WWII.

Detailed explanation-3: -The Germans employed radar on the ground and in the air for defense against Allied bombers. Radar was installed on a German pocket battleship as early as 1936. Radar development was halted by the Germans in late 1940 because they believed the war was almost over.

Detailed explanation-4: -Radar was a crucial part of the Dowding System, Britain’s highly effective and sophisticated air defence network. This system allowed Royal Air Force (RAF) Fighter Command to respond to incoming German attacks and use its precious resources of pilots and aircraft to the best possible effect.
