When was the first Radar used?

As we all know, Radar is an object-detection system that uses radio waves to detect aircraft, ships, spacecraft. I am sure, at least once in our lifetime, we would have seen it in our video games! So, apart from what you used it in your video games, "When was the first Radar used?". Let's explore!

British physicist James Clerk Maxwell developed equations governing the behavior of electromagnetic waves in 1864. Inherent in Maxwell’s equations are the laws of radio-wave reflection, and these principles were first demonstrated in 1886 in experiments by the German physicist Heinrich Hertz.. Christian Huelsmeyer proposed the use of radio echoes in a detecting device designed to avoid collisions in marine navigation. Christian Hulsmeyer was a German inventor. He is often credited with the invention of radar. His apparatus was called the "Telemobiloscope". However, it could not directly measure distance to a target, so it was not radar in the proper sense of Technology.

The first practical radar system was produced in 1935 by the British physicist Sir Robert Watson-Watt. In December 1934, Robert M. Page, working at the Naval Research Laboratory, demonstrated a full radar system.  The following year, the US Army successfully tested primitive, surface to surface radar. Great Britain was one of the leading developers of radar in the year before world war II.

On June 17th, 1935, radio based detection and ranging or radar, was first demonstrated in Great Britain. And by 1939 England had established a chain of radar stations along its south and east coasts to detect aggressors in the air or on the sea.  Radar stations were built around the British Isles to provide warning of an invasion from the air.

Germany was using radar by 1940 but Japan never used it effectively. The United States had a good radar system and it was able to predict the attack on Pearl Harbor an hour before it happened. 

Radar was used at first exclusively by the military. Now, radar is used by air traffic controllers to make sure that the planes do not collide with each other.
