摘要
分析了战术数据链自主时间同步机制及各类误差源特性,给出了降低时间同步误差源影响的设计途径。针对复杂物理环境下时钟漂移模型难以准确建立的问题,设计了一种基于自适应Kalman滤波的自主时间同步算法,提高了不利条件下数据链的时间同步性能,实验结果证明了所采用方法的有效性。
This paper analyzes the mechanism of autonomous time synchronization and the characteristics of various error sources in data link. The design way to reduce the influence of time synchronization error source is given. For clock drift model is difficult to establish under complex physical environment,an adaptive time synchronization filter algorithm is designed,which improves the time synchronization characteristics under adverse conditions,and experimental results demonstrate the effectiveness of the method used in this paper.
