Description

technical field [0001] The invention relates to the field of synthetic aperture radar satellite spaceborne task management, in particular to a target-oriented synthetic aperture radar satellite intelligent spaceborne task management method. Background technique [0002] Synthetic aperture radar satellite is a kind of ground remote sensing satellite with all-weather and all-weather detection capability. It has unique advantages in disaster monitoring, environmental monitoring, ocean monitoring, resource exploration, crop yield estimation, surveying and mapping, and military applications. With the wide application of satellites in various fields, the user's demand for synthetic aperture radar satellites is not only the functional requirements such as "clear" and "wide view" of static targets in known areas, but also for the vast unknown areas. Applied requirements such as "seeing independently" and "seeing quickly" for internally diversified objects. [0003] The application ...
