    The vehicle also features one of their Doppler weather radar brands. Eyewitness News is a style of television presentation that emphasizes visual elements and action videos, instead of the older ,"man-on-camera" style of newscast, [1] and is most prominently featured in the New York City metropolitan area.

  5. 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.

    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.

  7. ASR-11 - Wikipedia

    en.wikipedia.org/wiki/ASR-11

    The limited number of pulses sent out by the radar system has a direct effect on its ability to measure weather conditions. Unlike the ASR-9, the ASR-11 is less suited for wind shear detection, Doppler wind measurement, and precipitation reflectivity. The ASR-11 radar system will remain as is, with no further plans to upgrade the current ...
