Description

technical field [0001] The invention relates to the technical field of small satellite remote sensing simulation imaging, in particular to a small satellite mosaic imaging ground simulation system. Background technique [0002] On-orbit remote sensing satellites obtain ground observation target information through space-borne cameras, which have the advantages of long earth observation time and stable imaging, and are widely used in many fields such as weather forecasting, environmental protection, resource exploration, near-Earth observation, and military reconnaissance. The observation range of remote sensing satellites for ground target imaging has a great relationship with the imaging mode. For general static imaging, only one push-broom along the track is performed to obtain images of a certain width. Large observation range, therefore, in order to obtain remote sensing images of a larger target area in the vertical direction, the target area can be repeatedly pushed an...
