2. Weather radar - Wikipedia

   en.wikipedia.org/wiki/Weather_radar

   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.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the ...

3. List of radar types - Wikipedia

   en.wikipedia.org/wiki/List_of_radar_types

   The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. Weather radar; Wind profilers; Millimetre cloud radar; CODAR

4. NEXRAD - Wikipedia

   en.wikipedia.org/wiki/NEXRAD

   NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...

5. List of National Weather Service Weather forecast offices

   The National Weather Service operates 122 weather forecast offices. Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts. They also issue severe weather warnings, gather weather observations, and daily ...

6. Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Doppler_radar

   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 ...

7. Pulse-Doppler radar - Wikipedia

   en.wikipedia.org/wiki/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 the electronics .
