摘　　要：分析了弹载星敏感器在动态条件下的测角精度。明确了弹载星敏感器成像模型及其安装方式,并在系统设计所要求的动态条件下,定性定量分析了前向飞行和姿态变化所引入的像移量和测角误差。结果表明,前行飞行不会带来像移,姿态变化会带来像移。因而需要补偿姿态变化所引入的像移量,从而提高弹载星敏感器在动态条件下的测角精度。The dynamic angle measurement of missile borne star sensor is analyzed and the imaging model and the arrangement style of missile borne star sensor are presented. Qualitative and quantitative analyses of image motion and angle measurement error introduced by the missile forward flight and atti- tude change are made on the dynamic condition required by the system design. Results show that the forward flight will not introduce image motion but the attitude change will do so. Therefore, the image mo- tion should be compensated to improve the angle measurement accuracy of missile borne star sensor in dynamic conditions.
