靶场时统装置同步误差实时校准方法与分析

摘要

Deal with the question of synchronization errors calibration for that range clock synchronization systems can not be obtained in real-time when clock synchronization systems are actually working,a method based precision clock synchronization (PTP) was proposed and the uncertainties of the new realtime calibration system for clock synchronization systems synchronization error were analyzed and calculated.The experiment and analysis results show that the new method can achieve calibration for synchronization systems index 1 μs,and it can give the corrections of real time for synchronization errors.And it can meet the requirements for equipment information management.%针对靶场时统装置同步误差校准过程中无法实时获取校准结果的问题,提出了基于精密时钟协议(PTP)的时统装置同步误差远程实时校准新方法,对时统装置同步误差实时校准系统的不确定度进行了分析;实验与分析结果表明:新方法可对同步误差为1μs的时统装置开展实时校准,为事后的数据处理提供时间修正,也可满足靶场装备信息化管理需要.
