Abstract: The method of VISSR data buffering and processing is the key topic to design and manufacturing VISSR data processing subsystem for CDAS of FY 2 geostationary meteorological satellite.It will affect the accuracy and quality of the stretched Vissr(S.V.).The principle and calculating method of the processing model in which the data are first buffered and then resampled are discussed in this thesis.The technical way that the VISSR data are equal angle resampled using high speed parallel processor consisting of multi DSP is also introduced.
