The IMD has plans to replace its S-band 10 cm Cyclone Detection Radar (CDR) network with modern Doppler weather radars (DWRs) in a phased manner. Although the decision to set up the DWR network was taken in the 1990s and funds allocated, the first DWR units are being installed only in the 2000s.
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.
IMD became a member of the World Meteorological Organisation after independence on 27 April 1949. [5] The agency has gained in prominence due to the significance of the monsoon rains on Indian agriculture. It plays a vital role in preparing the annual monsoon forecast, as well as in tracking the progress of the monsoon across India every season ...

Doppler Radar image on Dec. 21, 2024 "At first glance, it seems like a pretty boring radar picture across the Northeast (Saturday) morning," said FOX Weather Senior Meteorologist Greg Diamond.
Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...
