Abstract:

With the basic principles of EKF and UKF, the target tracking methods of EKF and UKF based on observation distance are compared and analyzed.  The Matlab simulation results show that the fitting of UKF on real trajectory is more accurate. Meanwhile, it has smaller errors and better convergence as well.

Key words: EKF, UKF, observation distance, target tracking
