Abstract (en)
[origin: WO2020038985A1] The invention relates to a method for detecting a fluid, comprising at least one step of: - measuring, by at least one sensor (12), a wave propagating in an environment (11) of the wave, in order to obtain at least one measured signal, the wave particularly being a mechanical wave; - splitting the measured signal over a plurality of splitting time intervals with a predefined duration in order to obtain samples of the measured signal; - computing the temporal coherence of the samples; and - determining the presence of the fluid using the computed temporal coherence.
