基于无线链路的时钟同步技术

Clock synchronization based on wireless link

为了进一步提高在复杂电磁环境中的侦测灵敏度和分辨率,现代电子侦察系统正在朝着分布式的方向发展。针对分布式电子侦察系统中阵元间的时钟同步问题,提出了一种基于无线链路的时钟同步方案。该方案不需要铺设大量线缆,增强了阵列的灵活性和可扩展性。仿真结果表明提出的时钟同步方案的同步精度优于0.5ns。

To achieve further improvement in detection sensitivity and resolution under complex electromagnetic environment, modern electronic reconnaissance systems are going towards being distributed. Aiming at the synchronization of the clocks of different array elements in a distributed electronic reconnaissance system,a clock synchronization scheme based on wireless link is proposed. There is no need for plenty of cables in this scheme, so the flexibility and scalability of the array are enhanced. Simulation results show that the precision of synchronization is better than 0. 5 ns.
