TRACKING SYSTEM FOR TRACKING A MOVING SIGNAL SOURCE

摘要

An antenna tracking controller (102) for generating signals used to position an antenna for tracking a moving signal source includes a first Kalman filter (Figure 9) for estimating parameters of a first model of the motion of the moving signal source a second Kalman filter (Figure 9) for estimating parameters of a second model of the motion of the moving signal source. The second Kalman filter uses the parameters estimated by the first Kalman filter as initial values. A model quality charge/discharge is also provided to monitor the status of the data base.
