NEXRAD is a system of 159 high-resolution weather radars operated by the U.S. government agencies for detecting precipitation and atmospheric movement. It was developed and deployed from 1988 to 1997, replacing the previous WSR-57 and WSR-74 radars.
Doppler radar uses the Doppler effect to produce velocity data about objects at a distance by bouncing a microwave signal off them and analyzing how the frequency of the returned signal changes. Learn about the concept, technology, history and applications of Doppler radar in various domains like aviation, police radar detectors, navigation, meteorology, etc.
Weather radar, also called Doppler weather radar, is a type of radar used to locate and estimate the type of precipitation, such as rain, snow, or hail. Learn about the history, types, and applications of weather radar, and how it can detect severe weather and storms.
Learn about the principle, operation and types of continuous-wave radar (CW radar), a radar system that uses a stable frequency continuous wave to detect and measure objects. CW radar can be unmodulated or modulated by frequency, and is used for various applications such as altimeters, proximity sensors and missile guidance.
