Radar stands for Radio Detection And Ranging. Radar was originally called RDF (Radio Direction Finder) in Britain. A number of nations including USA, France, Britain, Germany and USSR were working on forms of radar prior to WWII, however the British were the first to put a working system into operation.
Radar!
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
No world is a stage, and you cannot detect a helicopter unless you have the radar station (radar alone is not sufficient)
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
