Abstract

Method for the detection of fluid leaks from underwater pipelines, according to which an acoustic signal is acquired from an area near the underwater pipeline, and is then transmitted to a processing unit of the signal itself; the processing unit eliminates from the signal the frequencies outside a certain determined frequency range in order to obtain a determined working band, which is shifted to lower frequencies in order to obtain two quadrature signals with half the band width around a zero frequency.
