The data frequency analysis method comprises: a step (310) for inputting signals coming from a first sensor; a step (315) for inputting signals coming from at least a second sensor, each second sensor being positioned close to the first sensor so that the signals coming from each second sensor are strongly correlated with the signals coming from the first sensor; a step of estimating, for each sensor, a transfer function or model established from the combination of the signals from the first sensor and from each second sensor; and a step (320) of extracting the structural properties of the system from each of the estimated models. |
