In view of multi-sensor trajectory correlation for theAdvanced-Surface Movement Guidance Control System(A-SMGCS),a trejectory correlation method is proposed.The method is combined with the federal Kalman filter based on distributed system to achieve the robust architecture,meanwhile it takes the features of the A-SMGCS and its sensors into consideration to reach the balance between efficiency and accuracy.Simulation experimental results show the proposed method is not only feasible but also with efficiency and accuracy.
