Abstract
The image rotation generated in the multi-parallel scanning process of a 45 degree rotary scanning mirror of a spaceborne infrared scanning imager is analyzed. A model for image correction is constructed. The generation mechanism of image rotation and image correction methods are described. Through the simulation analysis of remote sensing images, the validity and feasibility of the scheme to use a ground software to eliminate image rotation are verified preliminarily.
