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 ...
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 ...
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.

Shortly after coming to the station, Orr is credited with coming up with the name "Live Mega Doppler 3" for their radar. She also was the first to develop a summer series highlighting the Jersey Shore. For over 12 years "Orr at the Shore," aired on Thursdays between Memorial Day and Labor Day.
Raymond Pierrehumbert. Fred Sanders. Joshua Michael Aaron Ryder Wurman (born October 1, 1960) is an American atmospheric scientist and inventor noted for tornado, tropical cyclone, and weather radar research, the invention of DOW and bistatic radar multiple-Doppler networks.
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 .
The radar (ELM-2001) was installed on the Israeli "Kfir" fighter and went operational in 1974. Practical pulse-Doppler signal processing requires high-power light-weight solid state computing that became available in the early 1970s. The first aircraft to rely completely on its own radar system is the F-4 Phantom.
