    WAFF's "First Alert Doppler Radar" (formerly "Live Stormtracker Doppler"), which was located in Limestone County just off of US 72, was destroyed when it was hit by a large and violent tornado (which produced EF5 damage in nearby Tanner, approximately 10 miles (16 km) away from the radar site) on April 27, 2011. A camera mounted on the tower ...

    en.wikipedia.org/wiki/AN/AWG-9

    The AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B. [1] It is a long-range air-to-air system capable of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles simultaneously, using its track while scan mode.

  5. Mobile radar observation of tornadoes - Wikipedia

    en.wikipedia.org/wiki/Mobile_radar_observation...

    Mobile doppler weather radars have been used on dozens of scientific and academic research projects from their invention in the late 1900s. [1] One problems facing meteorological researchers was the fact that mesonets and other ground-based observation methods were being deployed too slow in order to accurately measure and study high-impact atmospheric phenomena. [1]

    As the storm crossed US 72 in eastern Limestone County, the tornado destroyed a Doppler radar operated by Huntsville NBC affiliate WAFF (channel 48) and continued into East Limestone, a heavily populated area of Limestone County where homes in subdivisions were damaged or destroyed at high-end EF3 strength.

  7. Terminal Doppler Weather Radar - Wikipedia

    en.wikipedia.org/wiki/Terminal_Doppler_Weather_Radar

    A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...

  8. Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Doppler_radar

    A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
