ANALYSIS METHOD OF AR MODEL FREQUENCY SPECTRUM BASED ON ACTIVE MONITORING SYSTEM

The AR model used to analyze driving response signal isconstructed. By the method, the degummed damage in alveolatecomposite structures is measured. Experiments on the method show thatAR model spectrum has the advantage of heving a continuous smoothcurve, by which the damage factor can easily be obtained. It will find applications in the quantitative analysis of active monitoring signals.
