摘　　要：文中提出一种基于LMS的动态时戳修正算法,对两个传感器的时钟源同步误差进行自适应估计,实现在GPS时钟源失效的情况下多传感器跟踪航迹同步融合。仿真结果表明,进行时戳动态修正的多传感器融合系统的跟踪精度明显好于未进行时戳修正的融合系统。The time-stamp correction online, based on LMS was proposed to estimate the time-source error between two sensors, and track synchronous fusion without GPS time-source was realized. The results of simulation show that the precision of tracking synchronous fusion is better than which hasn＇t been corrected statically after time-stamp correction online.
