摘　　要：对某遥感卫星红外扫描成像仪45°旋转扫描镜多元并扫成像中产生的图像像旋现象进行了分析,构建了图像校正模型。阐述了像旋产生的机理及图像校正方法。通过对遥感图像的仿真分析,初步验证了地面软件消像旋方案的正确性与可行性。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.
