The Invention of RADAR

The question of who should be credited with actually "inventing" radar is the subject of much debate, which is well beyond the scope of this page. In reality, it was the culmination of years of research done in several different countries. The "Doppler Effect" was first described by Christian Andreas Doppler in 1842, long before the invention of RADAR. However, a British man named Robert Watson-Watt received a UK patent for RADAR on September 17th, 1935. The first major application of RADAR was by the British in World War II. Their aircraft defense system was dubbed "Chain Home", and helped turn the tide of the war in Britain's favor. The term "RADAR" was coined by scientists in the United States Navy during World War II, and is short for "RAdio Detection And Ranging".
