How was the radar used in ww2?
How accurate is Doppler radar?
Doppler radar provided false positive results (rain event predicted but did not occur) 8.8% of the time and false negative results (failed to predict a rain event) 0.7% of the time.

When was the first weather radar system made?
During the early 1960s, the AN/FPS-68 and AN/FPS-81 “C” band weather radar systems were developed for the Navy. The FPS-81 was an improved version of the FSP-68. The U.S. Air Force also acquired some of the FPS-68 systems, and from them, the AN/FPS-77 “C” band system was developed.
When did the NWS start using s band radar?
Also in the 1970s, an “S” band version of the WSR-74 came into being. This radar has been used by the NWS for replacement of a number of older, difficult-to-maintain WSR-57 systems. During the same period, there have also been notable developments of weather radar equipment in Europe, Japan, Russia, and Australia.
