复合制导信息处理中的时钟匹配技术

Clock Match Technique in Combined Guidance Information Processing

在部分复合制导应用中,不同测量系统无法使用同一时钟,也无法完成系统对时,时钟不匹配将会产生较大误差。针对这种情况,文中使用线性插值时间校准方法来完成时间校准,并通过仿真分析了时钟匹配的影响以及测量值插值输出对减小误差的作用,结果表明测量值插值输出可以很大程度上改善误差,具有较强的工程实际应用价值。

In some combined controlling and guiding systems , different measurement units cannot use the same clock , also, time calibration cannot be completed , clock mismatch will bring great error .In this paper , the measured data interpolation method was introduced to reduce the error, and simulate the influence of clock mismatch and the role of measured data interpolation to reduce the influence .The simulation results show that this method can greatly improve the error and has significant practical value .
