An automatic method for synthetically preprocessing multi-source NOAA-AVHRR series and FY-1D 1A.5 data

摘要: Polar orbiting meteorological satellites have been used successfully in many fields which applications, such as dynamic monitoring, need multi-temporal remote sensing data imaged the same region but at different times and with sensors. The basis of these quantitative applications is automatic synthetic preprocessing satellite data. In order to ensure direct comparability multi-source National Oceanic & Atmospheric Administration-Advanced Very High Resolution Radiometer (NOAA-AVHRR) series FY-1D 1A.5 data, based on its imaging mechanisms, paper discusses radiant geometric methods for visual near-infrared thermal infrared channels. This performed by analysing technical parameters sensors, theoretical numerical simulation image comparison. For radiance preprocessing, calibration, spectral calibration sensors Sun elevation angles or zenith time are included. Based normalization spatial resolution scan-line directions, rough correction precise registration sequentially processed a higher precision. Combining detailed steps introduced paper, polar can be realized.
