摘　　要：介绍了三线阵CCD传感器的成像原理,分析了由于地球自转角速度的存在而产生三线阵CCD传感器像移的机理.在规划姿态跟踪策略的基础上,建立了有效成像面积和姿态机动方式的数学关系,求解关系式最大值以得到像移补偿的姿态跟踪机动策略.最后给出了姿态跟踪过程中的目标姿态和目标姿态角速度变化规律.A brief introduction of the theory of three-lines CCD camera is proposed and the mechanism of image motion loss of Three-lines CCD camera on account of earth rotation is presented. The mathematical relationship between the pattern of attitude maneuver and effective imaging area is set up based on the programming of tracking strategy of the satellite. The tracking strategy of the satellite is found when the mathematical expression gets the maximum value. Finally, the desired attitude maneuver angle and anglar velocity during attitude tracking are presented.
