摘要
捷联惯导系统动基座初始对准的研究中是假定运载体做恒定运动,而实际中运载体会改变运动状态,一些参数随之发生突变,使用卡尔曼滤波会造成跟踪误差增大。针对该问题,提出并设计了应用强跟踪滤波技术的捷联惯导系统动基座初始对准方案。通过数字仿真,将卡尔曼滤波与强跟踪滤波的性能进行比较,证明该方法具有精度高、抗干扰、跟踪能力强的特点。
At present, the research of SINS initial alignment on moving base focus on constant moving form. However, transporting species would change their moving form while moving with some parameters change in system, so using Kalman filter will increase the error. An initial alignment method was proposed by strong tracking filter. Comparing the performance of Kalman with STF, it is showed this method is with high accuracy, high anti-jamming and strong tracking ability.
