Abstract
In this paper, a four-element DFB fiber hydrophone array was constructed based on the wavelength division multiplexing technique, and the demodulation system of the four-element array based on PGC method was designed and realized. The static experiments of the hydrophone array system in the lake-test were conducted, and the results show that using PGC technology, the phase relationship of the demodulated underwater acoustic signal of each element in the array is stable, and the detection and localization of the target can be realized.
