摘　　要：惯导在动中通天线中起到隔离动载体角运动,确保天线波束指向稳定的作用,是动中通天线的重要组成部分。限于动中通天线的尺寸、成本等因素,无法安装高精度的惯导系统,同时载体上的高精度惯导与动中通天线的安装平面之间存在安装误差,限制了天线的指向精度。针对上述问题,提出了一种基于传递对准的安装误差估计方法,推导了包含安装误差角估计的速度/姿态角组合匹配模型的状态方程和观测方程,最后通过半物理仿真试验对方法的正确性进行了验证。The INS is a key component of SOTM antennas,and it plays the role of isolating the angular motion of the moving carrier and ensuring the directional stability of the antenna beam. The high-precision INS can＇t be installed because of antenna size and cost limitations.Meanwhile the installation error between the high-precision INS on the carrier and the plane of STOM antenna limits the antenna＇s pointing accuracy. Aiming at these problems,an installation error estimation method based on the transfer alignment is proposed,and the state equation and observation equation of velocity and attitude angle matching model including the installation error estimation are derived.Finally the correctness of the method is verified by semi physical simulation experiment.
