India Meteorological Department adopted radar technology for meteorological applications in the early 50s.The first indigenously designed
and manufactured x-band storm detection radar was installed in 1970 at New Delhi.
-
An integrated upper air sounding system comprising X - Band weather cum wind finding Multimet radar and radiosonde system (401 mhz ),
designed and produced indigenously, was introduced in 1975 in IMD at Bangalore.
-
The first S-Band cyclone detection radar became operational at Visakhapatnam in 1970.The first indigenous S-Band cyclone
detection radar was commissioned in Mumbai in 1980.
-
IMD now has a network of 10 S-Band cyclone detection radars covering the Indian Coast line. Six numbers in the East
Coast and four numbers in West Coast.
-
IMD’s network of X - Band radars consists of 29 radars comprising of 12 Storm Detection Radars (SDRs) and 17 Dual Purpose (Weather cum wind finding) radar.
-
IMD plans to replace all the existing old generation radars with state-of-art S-Band DWRs in a phased manner.
-
IMD has already installed 4 nos. S-Band imported DWRs at Chennai(2002), Kolkata(2003), Machilipatnam (2004) & Visakhapatnam(2006) replacing the old generation
S-Band cyclone detection radars at these places.
-
IMD has also installed one indigenous Doppler Weather Radar at Sriharikota (AP) in 2004, it was developed under MoU with ISRO Bangalore.
-
India Meteorological Department has a plan to install 2 more indigenous S-Band DWRs at Bhuj and Kochi to be developed by M/s BEL, Bangalore.
-
Under First Phase of modernisation, IMD also has a plan to replace old S–Band Cyclone detection Radar by S–Band Doppler Weather Radar at 12
locations namely Mumbai, Paradip, Nagpur, Patna, Lucknow, Patiala, Karaikal, Bhopal, Agartala, Mohanbari, Delhi and Goa.
