摘　　要：研究舰载导弹INS在低机动条件下借助海浪进行传递对准的问题.鉴于"线运动"+"角运动"测量匹配能以较低的机动要求而获得可接受的对准精度,基于"加速度"+"角速度"匹配法设计了一个对准滤波器,且对准滤波器采用较高更新率以克服加速度和角速度测量易受船体结构挠性变形和振动的干扰.为进一步减小船体挠性效应、降低对数据传输率要求并保持对准滤波器的快速收敛性,提出了测量数据预处理的方法.仿真结果表明:在低机动条件下实现舰载导弹INS传递对准具备可行性.The problem of aligning the ship - launched missile INS to the reference INS on shipboard is investigated by dint of the sea wave. An acceleration plus angular rate - matching filter is developed to provide alignment capability under low -g and low -rate ship maneuver, and high rate measurement processing is employed in order to overcome the ship flexure and vibration which inevitably disrupt acceleration and angular rate measurement. An approach with measurement pre - filter processing is proposed to further reduce unmodeled flexure dynamics and data transfer rate requirement while maintaining rapid convergence. Simulation results demonstrate the feasibility of the proposed approach for the missile INS transfer alignment under the low ship maneuver.
