Abstract:
This paper especially analyzes the basic principles and characteristics of extended Kalman filter(EKF)and unscented Kalman filter(UKF).Simulations are made in one-dimensional nonlinear tracking system and the moving base of strapedown inertial navigation systems(SINS)alignment.The results demonstrate that the precision of UKF is higher than that of EKF for the nonlinear system,and it can be widely used for the target tracking and the aerospace.
