摘　　要：同步实现是战术跳频电台最关键的技术。随着北斗卫星导航系统的正式运营,利用北斗无源授时服务提供的时钟作为战术跳频电台的同步参考时钟成为了可能。这种同步技术解决了用户位置容易暴露和用户数量容易饱和的问题,而且可以使初始同步和迟入网同步时间大大降低。对无源授时同步法的性能分析表明,这种同步方案实现简单,同步时间短、同步可靠性高、同步保持时间长,是战术跳频电台中非常具有前景的一种同步方案。Synchronization is the key technology of tactics FH radio sets. As the Beidou satellite navigation system, it is possible to use the time service as the source of synchronization referrence in Tactics FH radio. This synchronization scheme provides a feasible solution to the problem of exposure and saturation,and deeply decreases the time of preliminary synchronization and laggard synchronization. The performance analysis shows Beidou passive timing scheme is easy to realize followed by short synchronization time, high reliability and long holding time,and it is a kind of optimal synchronization scheme for tactics FH radio.
