| Abstract: | The AR model used to analyze driving response signal is constructed. By the method, the degummed damage in alveolate composite structures is measured. Experiments on the method show that AR model spectrum has the advantage of heving a continuous smooth curve, by which the damage factor can easily be obtained. It will find applications in the quantitative analysis of active monitoring signals. |
