Abstract(in English) | In measuring infra-sound produced by a mashine, the signal and wind noise with low friqency spectrum are obtained and have non-stational elements. The non-stational elements cause wind noise and short duration measurement. Mesured signal has trend part which is non-stational and the other part. The trend part mis separated by the Kalman filter based on IAR model and infra-sound is in the other part. By separation, the model for the infra-sound generator is indicated accurately. The proposed method works stably. From the obtained result, it is useful to estimated parameters of the space state model. |
