Abstract
Conventional linear array based on acoustic pressure hydrophone can not distinguish the target signal from the port side, so it can not locate the target accurately. The vector hydrophone has natural directivity and can be resolved from starboard to starboard after being formed. However, in practical engineering, it is necessary to further improve the resolution of starboard to starboard because of noise or interference, etc. A new method of port and starboard suppression based on directivity of vector linear array is proposed. The simulation results show that the starboard suppression ratio of vector beam output is enhanced. Experimental data processing results show that this method can suppress the starboard ambiguity of vector beamforming and improve the starboard resolution of vector linear array. The processing results verify the feasibility of the algorithm, and the algorithm has certain application value.
