It was being tested on December 7, 1941 when the Japanese were attacking Pearl Harbor, but when they saw evidence of a large number of airplanes comming in they thought it was a problem with the radar. The radar was working, the officers just didn't believe it. We had enough warning to have actually made a difference, but our military officers didn't trust the new technology.
The invention of radar is the outcome of the genius of many scientists and technologists. Christian Hulsmeyer for the very first time in history demonstrated the use of electromagnetic waves to detect distant metallic objects. He came up with a devise for the detection of metallic objects and demonstrated it in 1904 by identifying the presence of a ship in fog.
In 1917, Nikola Tesla, a mechanical/electrical engineer and inventor, established the principles related to frequency and power level for primitive radar units. Before the Second World War, the efforts of the American, German, French and British researchers as also the developments by the Soviets led to the creation of the modern radar equipment.
In 1934, Emile Girardeau, a French engineer obtained a patent for working on a dual radar system. Dr. Robert M. Page from America worked on the first monopulse radar during the same year. It was also during 1934 that the collaborated efforts of P.K. Oshchepkov, a Soviet military engineer, and the Leningrad Electrophysical Institute, brought about the creation of RAPID, an apparatus capable of detecting an aircraft within a range of 3km.
Several inventors, scientists, and engineers contributed to the development of radar.
German Christian Huelsmeyer was the first to discover the effect of radar in 1904, but radar as we know it was invented and the acronym established in 1935 by three British scientists, Sir Robert Watson-Watt, A F Wilkins and H E Wimperis along with Sir Henry Tizard discovered its use putting it to exellent effect in World War 2.
