Who invented radar system

Researchers and workers there made mass-production versions of the magnetron and developed about different radar systems. After the war, many peaceful uses for radar technology were found. Today air traffic control depends on radar to keep commercial aircraft from colliding. Radar is essential for tracking the weather.

The cavity magnetron is now used to cook food in microwave ovens. And many motorists have been caught speeding by police radar guns, including, reportedly, Sir Watson-Watt himself. APS News Archives.

Chain home radar station The Chain Home system worked fairly well, but it required huge antennas, and used long wavelengths that limited ability to pinpoint enemy aircraft accurately.

Young were able to detect basic continuous wave patterns made by ship and aircraft engines, by barely visible indications on an oscilloscope. By timing the pulses on an oscilloscope, the direction of the antenna revealed the angular location of the targets and equally important, range could be determined.

Together, the target was located. The rapid development and success of modern radar during WWII cannot be understated. It was crucial to ending the war in the Allies favor and sooner rather than later. A major development in the use of radar happened when physicists, John Randall and Harry Boot from the United Kingdom, invented the cavity magnetron 5,6 also in a device that shortened the pulse of radio wave energy and allowed for smaller radar systems as a whole.

By the end of the war, a wide variety of land and sea-based radars existed and the use of radar for civilian purposes became an exciting proposition. Smaller systems allowed for greater mobility and use over numerous platforms; all of this made radar systems more efficient and more accurate. When WWII ended, scientists and inventors focused on peaceful uses for radar. To these fields, the use of radar was a new and exciting concept. Hitler's strategic aerial onslaught, meant to clear the skies over the Channel and southeastern England preparatory to an invasion of the British Isles, might have succeeded if not for radar.

The RAF was outnumbered by the Luftwaffe, and radar saved already-stretched Fighter Command from having to maintain constant air surveillance. With radar providing an early-warning system, well-rested RAF pilots could be scrambled and rising to meet the incoming enemy formations in a matter of minutes. As the German fighters ran low on fuel and were forced to turn back, the Spitfires and Hurricanes could pick off the German bombers as they moved deeper into England.

The battle peaked during September and October
