摘要
传递对准时,飞机机翼的弹性变形会对挂在机翼上导弹的子惯导系统的对准精度产生很大的影响。本文研究了"速度积分"匹配传递对准方法,通过与速度匹配和"速度+姿态"匹配方法的仿真结果进行比较得出以下结论:"速度积分"匹配方法比速度匹配和"速度+姿态"匹配方法更适用于机翼存在较大弹性变形时的传递对准。另外,此种方法对由时间延迟所引起的时间标记偏差也有比较好的估计效果。
In transfer alignment,the alignment accuracy of the slave SINS is greatly degraded by the wing flexure of the aircraft.This paper deals with the transfer alignment method called ＂velocity integral＂ matching.By comparing with the simulation results of velocity matching and ＂velocity＋attitude＂ matching,we come to the conclusion that ＂velocity integral＂ matching is better than velocity matching and ＂velocity＋attitude＂ matching when the wing flexure exists.In addition,this method can also estimate the time-tagging error well which is mainly caused by the reason of time delay.
