Staring imaging method based on extended target point

The invention discloses a staring imaging method based on an extended target point, relates to the technical field of satellite attitude dynamics and dynamic optical imaging, and solves the problem that the staring imaging time and the coverage range of the inherent visual field range of a satellite are limited. The method comprises the steps of 1, determining the extended target point according to a target center point of task planning, wherein a distance between the extended target point and the geocenter is smaller than a distance between the target center point and the geocenter; 2, inputting the extended target point to a satellite attitude control system; and 3, controlling the satellite to perform staring imaging on the extended target point by the satellite attitude control system,wherein part of a formed image comprises the target center point, and the coverage overlapping rate of the two adjacent frames of images is larger than 50%. According to the method, the maneuvering capability and the imaging
