According to the characteristics of an air-borne opto-electronic tracking turntable and mathematics model of tracking turntable

a new adaptive filter based on angle changes of tracking turntable is presented to restrain the mechanical resonance of the opto-electronic trackng turntable under the conditions of mechanical structure and damp unchanged. The experiment results indicate that the maximum automatic traking error improves 3'. The proposed algorithm is a fast and stable algorithm

which can satisfy a real-time adaptive filter and restrain mechanical resonance perfectly. At present

this method has been applied to certain type of air-borne tracking turntable successfully.
