Abstract

An integrated demodulation system of optical fiber hydrophone array is designed in the paper for the application of oceanic oil exploration. The characteristic of artificial seismic signal, sensed and collected by piezoelectric hydrophone sensor used in the actual situation, is analyzed by joint time-frequency analysis. Based on this, parameters of the optical fiber hydrophone sensitivity and modulation frequency are designed with redundancy, ensuring that the upper limit of dynamic range of fiber optic hydrophone demodulation system can meet the requirements in the same operating conditions of sea trials, as those of piezoelectric sensor system.
