叙述了空空导弹惯导系统的对准原理与方法,包括粗对准和精对准两个阶段。在精对准中叙述了传递对准卡尔曼滤波器设计的准则,包括对测量模型、对准时间和对准精度的要求、机翼变形的影响、惯性仪表的误差及预滤波等因素的说明,并介绍了空空导弹惯导系统对准卡尔曼滤波器的算法方程及对准的步骤。 The alignment principle and method of inertial navigation system of air-to-air missile are described, including two stages: rough alignment and fine alignment. In precision alignment, the criteria for passing the alignment Kalman filter are described, including the description of the measurement model, the requirements of alignment time and alignment accuracy, the influence of wing deformation, the error of inertial instruments and the prefiltering , And introduces the algorithm equations and alignment steps for the AMIS alignment Kalman filter.
