摘　　要：针对有限资源下战术数据链自主时间同步问题,设计了一种基于Kalman滤波的时差数据处理算法和一种自适应的校时消息发送策略,有效降低了校时消息的资源占用率。此外,针对时间基准角色转移时造成Kalman滤波器发散的问题,提出一种解决方法,确保了时间同步功能的稳定性。实验与仿真结果证明了所采用方法的有效性。To address the issue of autonomous time synchronization of Tactical Data Link（ TDL） under the condition of limited resources,a time-difference data processing algorithm based on Kalman filter and an adaptive RTT message transmission strategy were designed,which effectively reduced the resource consumption rate of RTT messages.In addition,a corresponding solution was proposed for the problem of Kalman filter divergence caused by NTR role transfer,which ensured the stability of the time synchronization function.The experiment and simulation results have proved the effectiveness of the proposed method.
