ISRO launches Polarimetry Doppler Weather Radar of S-band at Sriharikota spaceport

ISRO chairman Dr. K Sivan has launched an S–band Polarimetry Doppler Weather Radar (DWR) at Satish Dhawan Space Centre in Sriharikota spaceport, Andhra Pradesh on September 16, 2018. This Radar was indigenously developed by Bharat Electronics Limited (BEL), Bangalore under Technology Transfer from ISRO. This is the 7th Radar manufactured in the country under “Make in India” Concept. The Doppler Weather Radar (DWR) is used for the observation of the weather system up to a range of 500 km and helps in early warning of severe weather events. The DWR provides detailed information on a storm’s internal wind flow and structure, while conventional radars are able to track and predict cyclones. The polarimetric capability of the DWR will significantly improve the accuracy of rainfall estimation leading to accurate and timely flash flood warnings.
