Doppler radar

Doppler radar is a specialised radar that uses the Doppler effect to produce velocity data about objects at a distance. It is capable of providing information on both the position of the target as well as its movement. It tracks the ?phase? of transmitted radio wave pulses. Phase means the shape, position and form of those pulses.
The Indian Meteorological Department uses the Doppler radar to track the movement of weather systems and cloud bands to keep an eye on the extreme weather events like cyclones and related heavy rainfall. The IMD?s Doppler radar in Mumbai stopped functioning while the city was witnessing rainfall.
