High Precision Time-frequency Synchronization Technology For Tactical Data Link
摘要
Abstract
In order to solve the problem of high precision time-frequency in signal-level cooperative operations in tactical da-ta link networks,a Local-Absolute-Relative synchronous time systems are designed in this paper.The time-frequency synchroniza-tion system in tactical data link network is managed as a whole.The time-frequency synchronization Kalman filter model is con-structed by using BDS/Data link/Clock fusion architecture.The simulation results show that,when the BDS system can be utilized for providing the timing information,the relative time synchronization precision and the absolute time synchronization precision,are better than 0.33 ns and 2.3 ns,respectively.Meanwhile,the frequency synchronization precision is better than 2.3E-10.On the oth-er hand,the time synchronization precision is better than 3.58 ns and the frequency synchronization precision is better than 2.6E-9 in BDS-denied environment.关键词
