基于信息融合和扩维Kalman滤波技术的系统误差估计算法研究

Research on Algorithm of Relative System Error Estimation Based on Information Fusion and Augmented Kalman Filtering

针对采用复合制导体制的面空导弹武器系统,目标支路和导弹支路分开后,引起中末制导交班误差增大,必须进行相对系统误差补偿,探讨了相对系统误差的估计技术。基于信息融合和扩维Kalman滤波技术,建立了估计模型和算法,通过2种不同情景的仿真,验证了模型和算法的正确有效性。

Technique of relative system error estimation is discussed,because of the increased handover error from the midcourse to the terminal of compound guidance surface to air missile weapon system after target tracking circuit and missile tracking circuit are separated.The compensation for the relative system error is needed.Estimation model and estimation algorithm are presented based on information fusion and augmented Kalman filtering.Two different simulation scenarioes are carried out in the end,which indica...
