摘　　要：采用四元数的传递对准是舰载垂直发射导弹一种有效的对准方法,提出了一种UKF滤波与卡尔曼滤波相结合的分段传递对准方法,推导了这种方法的数学模型,并对此方法进行了计算机仿真,结果表明,此方法不仅能高精度的估计出导弹的初始位置,还能有效估计出陀螺漂移。The transfer initial alignment of using quatemions is an effective approach for the vertically launched missile＇s alignment on warship. A kind of transfer initial alignment, which combined UKF with Kalman Filter and operates in two time stages was proposed and its model was derived. Then, the simulation was conducted to check the correctness of this alignment method. The simulation results show that, this method can estimate not only the initial position of the missile at high precision but also the gyros drift effectively.
