Optimized satellite image acquisition with regional reflectance characteristics
利用区域辐射特性优化获取光学遥感数据

A parameter optimization method with adjustment of integration time is proposed with analysis of the imaging process and the affecting factors. An imaging parameter setting model is brought up. The model parameter calculation and selection are discussed. Specific post-processing of the images acquired with the proposed method is analyzed. Experiment is carried out with Beijing-1 small satellite data for optimized imaging and comparison. Results show that images acquired with the optimized method have wider dynamic range and higher radiometric resolution, and with advanced information entropy and signal noise ratio.
