| 摘 要： | 现有的Link16网络同步算法，假定了询问与应答报文的传播时间相同，导致E值误差较大。提出一种改进算法，待同步JU相继向网内不同NTR发送询问报文，NTR分别发回应答报文。同时NTR间也发送往返计时报文，通过联立计算，提高时间误差的精度。改进算法的仿真分析结果，验证了新同步算法的可行性和有效性。

| Abstract: | Existing network synchronization algorithm of Link16 assumed that the propagation time of request and reply is equal, then caused the error of E larger. This paper proposed an improved algorithm, synchronizing JU successively send an inquiry message to different NTR within the network, then NTR respectively sent back a reply message. At the same time, NTR send RTT between themselves. It Improve the accuracy of the time error by simultaneous calculating. The simulation results of the improving algorithm verified its feasibility and effectiveness. |
