Development of underwater communication system based on vector sensor

The vector sensor is consisted of pressure hydrophone and hydrophone of vibration velocity,which could measures the orthogonal components of sound pressure and particle velocity co-locating and simultaneously. Comparing with traditional underwater acoustic system which just utilizes pressure information,vector sensor system processes sound pressure and vibration velocity information jointly in sound field. More information certainly brings better processing result. The underwater sound communication system which based on vector sensor is the instrument which makes use of the advantage of the vector sensor to improve the underwater communication quality. This paper discusses the main circuits and parameters. The feasibility of this system has been verified by experiment.
