摘　　要：提出了一种车载北斗卫星导航系统辅助下的岸舰导弹行进间弹载惯导对准方案。建立了岸舰导弹弹载惯导系统行进间对准的模型,在北斗卫星导航系统辅助下,通过双矢量定姿的惯性系粗对准和基于协方差自适应卡尔曼滤波精对准,实现岸舰导弹行进间对准,在岸舰导弹向发射场地的运动过程中实现弹载惯导对准。仿真试验表明:该方法在对准精度和对准时间方面均符合要求,能够很好地实现岸舰导弹弹载惯导系统快速发射和提高生存能力,可为岸舰导弹弹载捷联惯导系统在地面行进间对准的工程实现提供借鉴。Aiming at the needs of vehicle-mounted shore-to-ship missiles for rapid attack and flexible maneuverability,a vehicular Beidou satellite navigation system assisted by the missile-borne inertial navigation system during the course of the missile-borne inertial navigation system was proposed.A model for the alignment of the missile-borne inertial navigation system of a shore-to-ship missile was established.With the assistance of the Beidou satellite navigation system,the inertial system coarse alignment using dual-vector attitude determination and the fine alignment based on covariance adaptive Kalman filter were divided into two parts.The alignment between the shore-to-ship missiles can be realized in advance,and the missile-borne inertial navigation can be aligned during the movement of the shore-to-ship missile to the launch site.The simulation results show that the alignment accuracy and alignment time of the method both meet the requirements,and the effectiveness of the method was verified.The engineering realization of strapdown inertial navigation system alignment on the ground provides reference and reference.
