Evaluation method of Coastal Zone Imager performance based on remote sensing data analysis

With the rapid development of marine satellites in China, several marine satellites are about to be launched in recent planning. It is important to evaluate the payload performance of marine satellites, but the research on satellite load assessment is almost carried out for terrestrial satellites. The imaging region of the Coastal Zone Imager includes marine water bodies, so some assessment methods for estimating the performance of terrestrial satellites may not be applicable. In this paper, by analyzing and comparing the advantages and disadvantages of the current calculation methods of load performance evaluation, combined with the characteristics of the Coastal Zone Imager, the load performance evaluation scheme for Ocean color satellite is selected, and the real remote sensing data is used to verify the results.
