How Military Radar Works and When Was it Invented? – Radar is a very important military tool for detecting aircraft, vehicles, and missiles. Sonar is a technology that is widely used in submarines and other underwater vessels.
How Military Radar Works and When Was it Invented?
MilitaryEzyInfo.com – Radar is an abbreviation for radio detection and ranging. Radar is a system that uses electromagnetic waves (radio waves) to measure and map objects such as ships, airplanes, cars, and weather. The emitted electromagnetic waves become short-pulsed signals, which are partially reflected from the objects.
The Invention of Radar Was a Military Breakthrough
Many people believe that radar saved the British from defeat in the war against Germany. Radar was originally not used for military purposes, but for normal aviation purposes.
Many scientists developed radar, but the most important of them was Robert Watson Watt. He was a Scottish scientist who began his research on the radar in 1915.
Watson-Watt began his scientific career working on radiotelegraphy at the Meteorological Office in London. At the time, aircraft were increasingly being used for limited transportation and military purposes. He then came up with a device to protect aircraft from storms and other weather disturbances.
Watson-Watt began to focus on what was later called radar (radio detection and ranging). In the early 1920s, he joined the National Physical Laboratory. There, Watson-Watt researched and developed the navigation equipment and radio towers that supported radar research.
How Does Military Radar Work?
Radar works on the same principle as bats, flying at high speed through dark areas to avoid colliding with objects or each other. To use a radar, an antenna that emits radio waves is set up, and when it hits an object, the radio waves are reflected back.
By calculating the time it takes for the radio waves to hit the target and bounce back, radar can measure the distance to an obstacle or target.
As a result of this principle, many countries have begun to recognize the military potential of radar. Several companies, including those in the United Kingdom and Germany, are attempting to rapidly develop radar. Watson-Watt was given the task of developing radar by the Ministry of Aviation and Aircraft Manufacturing.
When Was Military Radar Invented?
In 1935, a radar was developed that could detect aircraft within 40 miles of the first signal, and by 1937, a radar network could be built to protect the entire British coastline.
In 1936, pulse radar, with its rhythmic interruption of the signal, was invented, and intergenic measurements could be used to determine the exact speed and direction of targets. This new invention had a profound impact on warfare and military technology.
In 1939, another very important breakthrough in radar development was discovered. It was the improvement of a powerful microwave transmitter. Watson-Watt put Britain ahead of other countries in the use of extremely accurate radar that was not affected by weather conditions.
This new radar was capable of transmitting very focused short waves. It also requires only a small antenna to receive the signal, making it easier and more convenient to mount on aircraft.
