摘要 通过建立动基座对准速度匹配的系统模型,对影响传递对准的一些重要因素如杆臂效应、挠曲振动等进行了分析,按照既定的载机机动方案采集飞行数据进行离线仿真。仿真结果表明,自适应卡尔曼滤波可达到对准时间15min,水平对准误差小于1′,方位对准误差小于6′,水平轴陀螺测漂小于0.02(°)/h的指标要求,证明S形机动速度匹配自适应卡尔曼滤波方案设计正确。利用机载试验数据进行的离线仿真验证,在将自适应卡尔曼滤波理论应用于工程实际方面以及对空中动基座对准方案的试验验证方面具有创新性。 By establishing the system model of moving-base alignment velocity match, the factors that influenced the transfer alignment were analyzed, such as lever arm effect, flexible vibrations, etc. The off-line simulation was made using the navigation data sampled from the trial in sigmoid flying. It is concluded that alignment precision satisfies the performance requirements, that is level 1′, azimuth 6′, platform-drift 0.02 (^o)/h, and alignment time 15 min. The simulation result shows the scheme proposed satisfies the system performance and is practicable.
