摘 要:研究了如何在战术弹道导弹 SINS上添加 GPS实现组合制导 .系统分析了战术弹道导弹 SINS/ GPS的不同组合模式及相应的数学模型 .分析了传统的卡尔曼滤波器算法的自身缺陷 ,设计了具有自动跟踪噪声统计性能的自适应卡尔曼滤波器 ,这种算法可以部分消除由于噪声统计性能的不确定性而对卡尔曼滤波器产生的不良影响 ,提高卡尔曼滤波器的滤波性能 .针对传统的卡尔曼滤波算法计算量大的缺点 ,将大系统分为若干个子系统 ,推导出了逐次正交化分布式卡尔曼滤波器算法 ,既保证了精度 ,又大大减少了计算量 .还分析了战术弹道导弹 SINS/ GPS组合制导的引入时机、制导方案的选择、对 SINS的校正方法 。This dissertation makes a systematic study about how to add GPS on strapdown inertial navigation system of tactical ballistic missile and realize SINS/GPS integrated guidance. Different modes of tactical ballistic missile SINS/GPS integration are systematically presented, and relevant mathmatical models are deduced. Disadvantages of traditional Kalman filter are analyzed, and a robust and adaptive Kalman filter has been designed. This nethod can partly eliminate the negative effect brought by the moise which cann't be stated accurately, thus can improve the capabilty and quality of the filter. Aiming at the disadvantage of large account quantity of traditional filter, the dissertation dispart a father system into several son systems, and deduce the gradually distributed filter arithmetic which can either decrease the amount of account or guarantee the quality of the filter. The dissertation also makes study about when to start integrating GPS with SINS, how to integrate GPS with SINS and how to correct SINS, Lastly decides the most feasible scheme.
