Historical Overview
|
Neither a single nation nor a single person is able to say, that he (or it) is the inventor of the radar method. One must look at the „Radar” than an accumulation of many developments and improvements earlier, which scientists of several nations parallelly made share. There are nevertheless some milestones with the discovery of important basic knowledge and important inventions:
|
|
| 1921 | The invention of the Magnetron as an efficient transmitting tube by the US-american physicist Albert Wallace Hull |
| 1922 | The American electrical engineers Albert H. Taylor and Leo C. Young of the Naval Research Laboratory (USA) locate a wooden ship for the first time. |
| 1930 | Lawrence A. Hyland (also of the Naval Research Laboratory), locates an aircraft for the first time. |
| 1931 | A ship is equipped with radar. As antennae are used parabolic dishes with horn radiators. |
| 1936 | The development of the Klystron by the technicians George F. Metcalf and William C. Hahn, both General Electric. This will be an important component in radar units as an amplifier or an oscillator tube. |
| 1939 | Two engineers from the university in Birmingham, John Randall and Henry Boot built a small but powerful radar using a Cavity-Magnetron. The B- 17 airplanes were fitted with this radar. |
| 1940 | Different radar equipments are developed in the USA, Russia, Germany, France and Japan. |
Driven by the common war expiry and the general development of the air forces to meaning key players radar technology undergo a strong development push during the 2nd's World War and is used during the „cold war” in large quantities along the german domestic border.
