| Abstract: | For overcoming the shortcoming of extended Kalman filter,the paper applies unscented Kalman filter on bearing-only target tracking problem. This algorithm has its theory basis consisted of Bayesian theory and UT transform,and implements according to the frame of EKF.The paper studies the UKF algorithm deeply,and brings forward a simulation example about bearing-only target tracking.The simulation results shows that the UKF algorithm improves stability and accuracy of filter,and its performance excelled general extended Kalman filter,and the UKF has broad application prospect. |
