摘要: 从发射准备时间和对准精度等方面分析现代战争环境下车载导弹对初始对准的要求,提出利用自准直仪进行光学辅助数学传递对准的方法。给出光学辅助数学传递对准系统搭建方案,推导主、子惯导方位光学传递关系,将光学准直得到的相对方位测量角引入到“角速度+加速度”匹配模式中构成新的量测方程,对主、子惯导安装角进行滤波估计。在实验室条件下对方位光学传递算法的正确性和精度进行了验证,并对光学辅助数学传递对准方法进行了数学仿真分析,仿真结果表明,该方法具有较快的对准速度和较高的对准精度,能够满足现代车载导弹快速高精度初始对准的要求。

Abstract: The requirements of vehicle-launched missile for the initial alignment in modern warfare are analyzed from the aspects of launch preparation time and alignment accuracy. A new alignment method combining optical collimation and transfer alignment is proposed. A system construction scheme is proposed, and an optical azimuth transitive relation between master inertial navigation system (MINS) and slave inertial navigation system (SINS) is derived. The relative azimuth obtained by optical collimation is introduced into the measurement equation of “ angular rate plus acceleration matching” to estimate the installation angle between MINS and SINS by utilizing the Kalman filter. In the laboratory, the principle experiment is implemented to verify the optical azimuth transfer algorithm. The mathematical simulation for optically-aided transfer alignment is carried out. The simulation results show that the proposed method has fast convergence speed and high alignment accuracy to meet the demand of the initial alignment of modern vehicle-launched missiles.
