In a TV tracking system ,the time delay and jump of TV miss distance will have a relative large influence on stability and tracking accuracy of control system .In order to solve the problem ,Kalman filter is designed for prediction target,s moving parameters (position and velocity) according to the realtime property and accuracy demands of the tracking and control system .The simulation shows Kalman filter can predict the position and velocity of target according to measured data.Overshoot is 18% ,transition time ts is 06 s.
