Re: ISRO Cyclone
As you Asking for the Information About the Satellite for Weather Forecasting, Cyclone Detection and Tracking of ISRO the Information is given below SCATSAT-1 is the continuity mission for Scatterometer payload carried by the earlier Oceansat-2 satellite. The magnitude and direction of the wind vector at the ocean surface is a key parameter for weather prediction as well as detection and tracking of cyclones. The objectives of SCATSAT-1 are to facilitate the weather forecasting services to the user communities through the generation of wind vector products. Working of the Statellite : The satellite is carrying a Ku-band Scanning Scatterometer radar instrument operating at 13.515 GHz similar to the instrument flown onboard Oceansat-2. Scatterometer operates on the principle of radar. When the radar radiates energy pulses towards the ocean’s surface, a backscatter effect is produced due to interaction between electromagnetic waves and sea surface waves, which is function of speed and direction of surface winds over the oceans. This process of receiving back-scattered signal is carried out while conically scanning or rotating the antenna along with the motion of the satellite giving a swath of 1400 km. The collected data is processed onboard to generate estimate of backscattered power/signals and stored on a data recorder. This recorded data is then transmitted to ground station which is converted into wind vectors for the global user. |
