WSR-74. WSR-74C radar from Central Illinois WFO. WSR-74 radars were W eather S urveillance R adars designed in 1974 for the National Weather Service. They were added to the existing network of the WSR-57 model to improve forecasts and severe weather warnings. Some have been sold to other countries like Australia, Greece, and Pakistan.
The radar network consisted of WSR-57 developed in 1957, and WSR-74 developed in 1974. Neither system employed Doppler technology, which provides wind speed and direction information. The Joint Doppler Operational Project (JDOP) was formed in 1976 at the National Severe Storms Laboratory (NSSL) to study the usefulness of using Doppler weather ...
ARMOR is a modified WSR-74 C-Band (5625 MHz) radar with a 0.5 - 1.0° resolution in azimuth and a spatial resolution varying from 60 to 500 meters, with a typical resolution of 150m. ARMOR sits 206 meters above sea level. The pulse length can vary from 0.4 to 4 microseconds and its peak power is 350 kW.
The WSR-57 (Weather Surveillance Radar - 1957) was the first 'modern' weather radar. Initially commissioned at the Miami Hurricane Forecast Center, the WSR-57 was installed in other parts of the Contiguous United States (CONUS). [2] The WSR-57 was the first generation of radars designed expressly for a national warning network.
In 1975, the production of the WSR-74 line of radars, mostly C-band, began. It produced cavity magnetron and klystron commercial S and C-Band weather radars began. [ 1 ] Also in 1974, EEC was selected by the US National Weather Service to deliver 160 WSR-74 radar systems to replace the older models across the country. [ 1 ]

Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The majority of Australia's weather radars are operated by the Bureau of Meteorology (BoM), an executive agency of the Australian Government. The radar network is continually being upgraded with new technology such as doppler and dual polarisation to provide better now-casting. Doppler weather radars are able to detect the movement of ...
