Zusammenfassung: | The invention discloses a high-frequency wide-width imaging method based on linkage of a space-based platform and an epicyclic rotating mirror, and relates to the technical field of space optical remote sensing. In order to solve the technical problem that the existing conventional push-broom imaging and swing mirror dynamic scanning imaging methods and the like are difficult to realize ultrahigh frequency sub-wide coverage revisit to the ground, the method comprises the following steps: firstly, calculating a visual angle under a load, a geocentric angle corresponding to a ground scene and the width of an imaging strip along a rail direction; setting an imaging initial state; then, the space-based platform is controlled to quickly perform attitude maneuver, and the revisit frequency and the overlapping rate are greatly improved; meanwhile, the multi-surface rotating mirror is controlled to perform periodic rotating motion to adjust the optical axis for scanning, so that the imaging range is effectively expan |
