WSR-57

The WSR-57 (Abbr. of Weather Surveillance Radar 1957) was the radar chosen for the first operational weather radar network of the National Weather Service (a local forecast office). It was a classic non-coherent radar and could measure reflectivities only. Its military designator was AN/FPS-41, because the Navy ordered sets of this radar. The WSR-57 was designed in 1957, and operated at S-Band or 10-cm wavelength, chosen to minimize the undesirable effects of signal attenuation by rainfall experienced on the AN/CPS-9 3-cm wavelength radar. The weather warning network was implemented in 1959 with the installation of 31 WSR-57s. By the mid-1960's there were 45 radars around the U.S. in each a distance of around 200 miles.

The first WSR-57 was installed at the Miami hurricane forecast center in 1959. The last WSR-57 radar was decommissioned in Charleston on December 2. 1996.
