Problems solved by technology

However, there are currently the following problems: 1) The optical remote sensing imaging simulation and ground processing are still analyzed, designed and used as independent units, and the ground processing cannot be regarded as an organic link of the full-link imaging system, and the optical remote sensor is developed from the perspective of the whole system. Optimum design; 2) Imaging simulation estimation focuses on relatively independent model and method research, and has not yet formed a serial simulation platform for all links of the optical remote sensing link from scene simulation to atmospheric environment simulation to satellite and load simulation. ; 3) A comprehensive quality analysis and test platform for the whole system of optical remote sensing satellites from scenery, atmosphere, satellite, data transmission, compression to ground processing to image quality evaluation has not yet been established
