Radar was first used to measure the speed of a moving object in 1935. By 1938, they were used to measure the speed of a fastball thrown by Bob Feller.
RADAR was first used to clock pitching speed in 1972. Earl Weaver was the first person to use the RADAR gun to determine speed in baseball.
The exact location of where the first Doppler radar system was used cannot be determined because the first radar systems were mobile.
World War 2 saw the first wartime use of radar.

First of all, they are not strictly speaking Radar instruments- they are photoelectronic timing lights- somewhat similar in principle to those used at Drag strips ( and control-sequenced by staging, stand-by, etc timing lights the signal complex being called a Christmas Tree= the apparent procession is from top to bottom- akin to highway traffic lights. These devices are NOT Radar and have never been considered Radar devices- The acronym stands for Radio Direction and Ranging- measuring the velocity of a baseball over what amounts to a fixed course ( pitcher"s mound to plate) cannot be considered direction finding. Nor are they similar to police radar- but are closer to that, than tradition Radar as used on ships, for example. This techno practice- I believe was first used in technologicaloly savvy Japan- and on TV casts was used on every pitch- some years in advance of the stateside deployment. Technically, these devices are not Radar at all but timing lights or electronic chronographs.
