摘　　要：为了对桅杆型光电探测系统在方位方向的精度进行分配与分析,提出将光电探测系统与桅杆平台系统统一分配的方法。根据系统总体指标精度将误差值分别分配到光电探测系统与桅杆平台系统。根据系统参数指标计算这种精度分配是否满足精度要求。采用内场实物试验验证桅杆型光电探测系统方位方向精度分配方案的合理性。计算与试验得到的光电探测系统自身在方位方向的误差值分别为1.2″和1.9″,均小于分配值2″.计算与试验得到的桅杆平台系统的误差值分别为19.7″和23.5″,均小于分配值24″.计算与试验得到的系统总误差值也小于总体指标25″.A method of how to uniformly distribute the accuracy on the azimuth direction of the opticelectronic system and mast platform system is put forward. This method is used to distribute and analyze the accuracy of the mast-mounted photodetection system. The overall accuracy index is separately distributed to photodetection system and mast platform system. This accuracy distribution is calculated based on the system parameters to prove whether it could satisfy the accuracy requirement. The rationality of accuracy distribution approach of the mast-mounted photodetection system is validated through infield experiment. The calculated and experiment error values of azimuth direction of the photodetection system are 1.2″ and 1.9″, respectively, which are less than 2″. The calculated and experiment error values of azimuth direction of the mast platform system are 19.7″and 23.5″, which are less than 24″. The overall calculated and experiment error values of the system are less than 25″.
