Claim Text:
1. A stabilization control method for a satellite tracking antenna, the method comprising: outputting a monopulse signal and a gyro signal through a satellite tracking antenna having a gyro mounted thereto, under a situation that disturbance is applied to the satellite tracking antenna; inputting the output monopulse signal and gyro signal into a Kalman filter for stabilization of the satellite tracking antenna; defining a state vector of the Kalman filter based on a pointing error angle for the satellite tracking, corresponding to the monopulse signal, and a pointing error angular velocity for the satellite tracking, corresponding to the gyro signal; predicting an original monopulse signal corresponding to a state prior to distortion of the monopulse signal based on the defined state vector, and continuously updating the prediction of the original monopulse signal; and carrying out the stabilization control for the satellite tracking antenna by using the predicted original monopulse signal as a pointing-error-correcting input value.
