我国正处于海洋高频观测的发展阶段，作为海洋观测的一个重要途径，静止轨道海洋成像辐射计的发展具有重要的战略意义。本文分析了静止轨道二维指向面阵成像光学系统所引入的像旋误差，提出了针对面阵误差的图像消旋算法，并且给出了消旋算法有效性的验证方法。经验证，本文提出的消旋算法，消除了39%像面旋转的影响，可以大大提高二维指向成像的地理定位精度，提升遥感仪器的准确度，因此本工作为二维指向面阵成像系统后续图像处理奠定了基础。

Our country is at a developing stage in the area of high-frequency observation of oceans. As an important approach of observation of ocean, the development of the geostationary ocean radiometer is of great significance. In this paper, we analyze the image rotation errors introduced by the optical system of plane imaging with two-dimensional pointing reflection mirror, propose the image rotation elimination method for two-dimensional scanning and the verification method. It is proved that the proposed rotation elimination method can reduce 39% of image rotation. This indicates that the algorithm greatly improve the accuracy of two-dimensional directional imaging and improve the accuracy of remote sensing instruments. Therefore, the work lay a good foundation for image processing in two-dimensional pointing plane imaging system.
