    en.wikipedia.org/wiki/Terminal_Doppler_Weather_Radar

    Terminal Doppler Weather Radar (TDWR) is a Doppler weather radar system with a three-dimensional "pencil beam" used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States. [1] As of 2011, all were in-service with 45 operational radars, some covering ...

    Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...

    Doppler on Wheels. DOW 7 on display at the USA Science and Engineering Festival in 2010. Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Illinois [2] and led by Joshua ...

  7. Pulse-Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_radar

    Pulse-Doppler radar. A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of ...

    In addition to its main studios, WWTV/WWUP operates two news bureaus in Traverse City (located on Aero Park Drive, near Cherry Capital Airport) and Petoskey. During its weather forecasts, WWTV/WWUP uses live, NOAA National Weather Service radar data from several regional sites. This data is presented on-screen as the "Doppler 9&10 Radar Network".
