中文摘要：

星敏感器像移模型是星图运动补偿算法的关键技术，也是动态星模拟算法中的重要组成，它为高分辨率星敏感器的全链路运动模糊的建模仿真提供支撑。首先，借助正态分布的静态星像能量模型，引入星像移速度，得到匀速运动星像的能量分布函数。其次，为了获取星像移速度，研究了两种解算方法：（1）基于坐标系转换的星像移模型；（2）基于星光矢量旋转的像移几何模型。最后，建立仿真环境，通过调整积分时间、三个姿态角变化率、发射时间、地点、观星时弹体姿态角等输入参数，可以获取弹载星敏感器在轨运动时观测星像的重要仿真数据：如导航星信息，像移大小、方向，灰度分布，信噪比等。这对星图运动补偿算法的研究和评价都显得十分必要。

英文摘要：

Image motion model on star sensor is an important component of dynamic simulation algorithm of stars, and it lays the foundation for motion blur modeling simulation of high resolution star sensor. Firstly, with the help of the normal distribution of static star image energy model, introducing the star image motion speed, the energy distribution function of moving stars was obtained. Secondly, in order to obtain the star image motion speed, two solution methods were studied： （1） star image motion model based on the coordinate transformation, （2） image motion model based on the stellar rotation vector. Finally, the simulation environment was established. Through adjusting input parameters such as integral time, rate of change of three attitude angle, the launch time, location, important simulation data of stars observed by star sensor in orbit could quickly be obtained, such as navigation stars information, value and direction of image motion, intensity distribution, signal to noise ratio. This work is very important to study and evaluate the star image motion compensation algorithm.
