摘　　要：导弹的惯导系统初始对准时间和精度直接影响武器装备的机动性和打击精度,如何缩短弹体惯导系统的对准时长以减少车载陆基导弹发射准备时间是各国装备研发人员的重要研究方向。以基于捷联惯导系统的车载陆基导弹行进间快速对准技术为研究对象,对车载主系统和弹载子系统的动态快速传递对准原理进行了分析,建立了详细的误差模型,并进行了多种载车行进状态下的仿真分析和实验验证。研究结果表明,采用动态传递对准的方法可实现子惯导系统在50s内对准过程的姿态收敛,实现了对多种动态情况下的子系统对准精度和对准时间的分析和评估,验证了所提出方案的可行性与准确性。The initial alignment time and accuracy of inertial navigation system(INS) directly affect the maneuverability and strike accuracy of weapon equipment. How to shorten the alignment time of missile INS to reduce the launch preparation time of vehicular missile is an important research direction of equipment researchers in various countries. In this paper, taking the fast dynamic alignment technology of vehicular missiles based on strapdown inertial navigation system(SINS) as the research object, the transfer alignment principle of vehicular main system and missile-borne subsystem is analyzed, the detailed error model is established, and the simulation analysis and experiment verification under various vehicular moving states are carried out. The results show that the attitude convergence of SINS could be achieved within 50 s by using the dynamic transfer alignment method. The alignment accuracy and time of SINS under various dynamic conditions are analyzed and evaluated, the feasibility and accuracy of the scheme are verified.
