鉴于光电侦察定位系统的设计、验收、订购阶段均涉及对系统精度的评价，指出影响光电侦察系统目标定位精度的评价指标。研究了均方根误差、平均误差及置信概率区间方法的计算原则及使用条件，给出光电侦察系统目标定位精度的评价指标，并提出设计阶段的精度预估方法、验收阶段的精度评定方法以及设备采购阶段的性能优选方法。规范了光电侦察系统的定位精度预估、验收以及订购。

The target location accuracy evaluation index of electro-optical reconnaissance system was investigated. Based on the research of root-mean-square error (RMSE), average error, and confidence probability, the accuracy evaluation methods of location, attitude, direction, distance were discussed and the optimal selection of various equipments was given, which would standardize the design and acceptance of the electro-optical reconnaissance system.
