Original Abstract Submitted
A hydroacoustic wave detection system that comprises a time delay generator and a hydroacoustic wave detector. The time delay generator is connected to an end of an underwater cable in which light signals travel in an optical fiber system in the underwater cable. The time delay generator is configured to introduce a time delay in the light signals received by the time delay generator to generate delayed light signals. The hydroacoustic wave detector is configured to control the time delay generator to generate a number of time delays. The hydroacoustic wave detector is configured to detect a presence of hydroacoustic waves for an event (e.g. underwater earthquake, underwater volcano, whale call) from an interferometric response determined using the light signals transmitted and the delayed light signals received. The hydroacoustic waves impinge on the underwater cable at a perturbation location along the underwater cable.
