机载导弹捷联惯导系统快速传递对准方法研究

Research on rapid transfer alignment for the airborne missiles SINS

针对速度、位置匹配方法的局限性 ,推导了捷联惯导速度加姿态角匹配传递对准模型 ,进行了机翼的挠性分析 ;设计了以滚动机动为主的 Wing Rock和 Pop Up两种机动方式 ,并进行了速度加姿态角匹配对准仿真。仿真结果表明 :采用所述方法 ,可将传递对准过程由几分钟降低到几秒钟 。

The velocity/position matching, which was widely used till now, is limited in use for the new air weapons. The velocity/attitude matching transfer alignment procedure is modeled and the flexure model of the aircraft wings is analyzed. The ways of WingRock and PopUp circle maneuver are designed. Velocity/attitude matching is simulated using them. The results show that the time of transfer alignment procedure can be reduced to seconds from minutes and has a precision of milliarc.
