Christian Andreas Doppler
Doppler RADAR is named after Christian Andreas Doppler. Doppler was an Austrian physicist who first described in 1842, how the observed frequency of light and sound waves was affected by the relative motion of the source and the detector. This phenomenon became known as the Doppler effect.
The first practical radar was invented in 1935 by Sir Robert Watson-Watt was used for enemy planes and ships that the Germans might encounter during World War II.
After World War II, the radar was used in many other different wars until the 1960's, when the National Weather Service began experimenting with Doppler radar for weather detection. In the late 70's and early 80's, Doppler radar was beginning to be used at television stations. In 1982, a similar version of the Doppler radar was added on to the Weather Service weather radar in Montgomery, Alabama. This radar was improved in 1985 and started appearing in other Weather Service areas across the nation. Today, the newest version of the Doppler radar is the NEXRAD. These radars are more powerful and have more features than any radar in history.
