The Early History of Radar [Historical]

The history of radar has often been told by the nations who used it to win World War II (WWII). History books often stated that radar won the war for the Allies. This is probably an overstatement, as both sides used radar. Research on radar started in eight nations well before WWII: France, Germany, Italy, Japan, The Netherlands, the Soviet Union, the United Kingdom, and the United States. The first evidence of the radar principle sprung from wireless technology as early as 1897, when Alexander Popov observed interference caused by a passing ship while he was transmitting wireless signals.
