中文摘要：
为了减小ATP系统的像差对对准的影响,达到提高系统的对准精度的目的,文中以星间ATP系统中的高精度对准平台为基础,分析了激光器处于轴外发射状态时需要考虑的两个位置偏移量（离轴参量h/s和偏移参量ra）,提出激光器的位置状态会对像差有着一定的影响。并通过数值仿真,分别分析了在存在激光器位置偏移量时各种像差对对准精度的影响情况。结果表明激光器发射的状态明显影响着像差对对准的影响程度,适当调节激光器发射状态有利于减小像差对对准精度的影响,进而提高对准精度。
英文摘要：
In order to reduce the effect of aberration on the alignment and enhance the system alignment accuracy in a ATP system,this paper analyzes two position laser displacement（h/s and ra）.It also points out that the two position laser displacement will influence the aberration.This paper has respectively analyzed the effect of a variety of aberrations on alignment precision in the presence of position laser displacement through numerical simulation.The results show that the state of laser emission significantly affects the aberration′s influence on the alignment.Appropriate adjustment to the state of laser will reduce the effect of aberration on alignment and improve the alignment accuracy.
