| 摘 要： | 为了解决INS/SMNS(Inertial Navigation System /Scene Matching Navigation System)组合导航系统信息融合时涉及到的时间对准、多速率滤波、不等间隔以及量测滞后等问题,根据INS/SMNS组合导航主要应用于末制导段以及Kalman滤波与观测值的关系,提出了采用外推法进行时间对准、变周期离散化进行不等间隔多速率滤波、使用计算机软件消除量测滞后的解决方案.对比分析了常规Kalman滤波、消除量测滞后Kalman滤波以及方案的滤波精度.仿真结果表明设计的方案具有较高的滤波精度.

| Abstract: | The problems,such as time alignment,multi-rate filter,unequal interval and measurement delay,were involved when information was fused in inertial navigation system /scene matching navigation system(INS/SMNS)integrated navigation system.In order to solve them,a solution,based on the fact that INS/SMNS integrated navigation system was applied in terminal guidance generally and the relation between Kalman filter and measurement,was presented.Extrapolation was applied to the align time,the system was discretize... |
