TAMDAR observations include temperature, pressure, winds aloft, relative humidity, icing, and turbulence information which is critical for both aviation safety, the operational efficiency of the U.S. National Airspace System (NAS), and other world airspace management systems as well as other weather-dependent operational environments such as maritime, defense, and energy.
[2] [3] One of the parent companies, WLLX, a radio station in Lawrenceburg, Tennessee, has owned a weather radar since 1987 for general precipitation observing. On February 5, 2020 , an EF-1 tornado impacted the town of Lawrenceburg [ 4 ] with little warning, leading to discussions of the necessity of better warning processes. [ 5 ]
[1] 128 of the WSR-57 and WSR-74 model radars were spread across the country as the National Weather Service's radar network until the 1990s. [7] The WSR-57 radars were gradually replaced by the Weather Surveillance Radar - 1988, Doppler, WSR-88D, which NOAA named the NEXRAD network. The last WSR-57 radar in the United States was decommissioned ...
The Weather Service Office of Nashville was awarded the United States Department of Commerce Bronze Medal Award for superior federal service three times, in December 1998, May 2007, and April 2010. All three instances were for providing life-saving services for the three major tornado outbreaks that occurred in Middle Tennessee in April 1998 ...
The Zaslon is a pulse-Doppler radar with a passive electronically scanned array (PESA) antenna and digital signal processing. The antenna used by the Zaslon is actually a multi-channel system comprising two separate electronically controlled arrays, an X band radar with 1700 emitters and a L band transponder with 64 emitters brought together into a single antenna.

The Western Electric System 1393 Radar Course Directing Central [2] (RCDC) was a Cold War complex of radar/computer systems within the overall Improved Nike Hercules Air Defense Guided Missile System (separate from the missiles, storage and launch equipment, and command post equipment).
The station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. The station was re-designated as Lake City AFS, TN, on 1 December 1953. An AN/FPS-6 height-finder radar was added in 1958. One ...
The Type 271 was a surface search radar used by the Royal Navy and allies during World War II.The first widely used naval microwave-frequency system, it was equipped with an antenna small enough to allow it to be mounted on small ships like corvettes and frigates, while its improved resolution over earlier radars allowed it to pick up a surfaced U-boat at around 3 miles (4.8 km) and its ...
