摘要
针对实时测速定轨 (即只用测速数据确定运动目标的状态参数 )的实现问题 ,研究了一种扩展 Kalman滤波方法 ,并利用其状态方程和线性化观测方程得到定轨算法。理论推导和仿真结果表明 ,此算法是收敛的 ,且精度较高。
As far as the real time data processing of MVMTTS (multi velocity measuring trajectory tracking system) is concerned,the observation equations and state equations of extended Kalman filter are deduced.And the precision of data fusion is provided.Theoretical analysis and simulation show that the method is applicable to data processing in space flight.
