The basic principle and method for target motion analysis based on bearing measurements of two arrays is studied in this paper. The algorithm of Kalman filter estimation is presented. The simulation results show that the movement factors of target can he fast and steadily estimated using extended Kalman filter. At the same time, the influence of the bearing data association, space between two arrays and the error of bearing on the tracking performance is shown and references to engineering application are provided.
