The First Radar...

Thursday, December 11, 2008

Radar is short for RAdio Detection And Ranging. Radar is used to locate distant objects by sending out radio waves and analyzing the echoes that return. Radar can determine where a distant object is, how big it is, what shape it has, how fast it's moving and in which direction it's going. Radar is now used to watch developing weather patterns, to monitor air traffic, to track ships at sea, and to detect missiles.
The first practical radar system was invented in 1935 by the Scottish physicist Sir Robert Alexander Watson-Watt (April 13, 1892-December 5, 1973). He developed radar to help track storms in order to keep aircraft safe. His invention eventually helped the allies win World War 2 against the Germans.
