C-Band Polarimetric Doppler Weather Radar (DWR)
C-Band Polarimetric Doppler Weather Radar (DWR)
Product category :Weather Radar
The C-band polarimetric Doppler Weather Radar is a state-of-the-art indigenous Radar. The Radar development is an initiative by ISRO as a national effort to design and develop indigenous Weather Radars to meet the country’s weather forecast requirements. The vision is to establish a network of Weather Radars to seamlessly cover the entire country and thereby ensure effective detection of severe weather conditions, cyclone warning and appropriate weather forecasts. Dual polarimetry is implemented for effective rain estimation and hydrometeor classification.
This radar provides long range weather surveillance up to 500 kms. It operates in S-band and is capable of detecting and estimating the parameters of cyclone and other severe weather conditions. This Radar can forecast severe weather conditions so that necessary preventive steps could be taken to alleviate the impact of such natural disasters in terms of loss of life and property.
