摘　　要：本文通过介绍偏流角的产生原因以及星载三线阵CCD相机的成像特点,结合具体算例分析了偏流角以及剩余偏流角对星载三线阵相机摄影的影响,提出为了保证三线阵影像的有效立体重叠,必须对偏流角进行修正。In this paper,the cause of drift angle and the imaging principle of three-line array CCD camera are introduced firstly.Then the influence of drift angle and residual drift angle on satellite photography of three-line array camera is analyzed by an example.At last,the conclusion that the drift angle of satellite photography should be corrected to improve the stereo overlap of three-line array images is drawn.
