  • The vector hydrophone is composed of three spatially co-located but orthogonal oriented velocity hydrophone plus another co-located pressure hydrophone. To understand the performance of DOA estimation using vector hydrophone array in a reflecting boundary, based on the reflecting model of plan acoustic wave, the improved Bartlett and Capon spatial spectrum are presented, and then the general frame is set up. The ability of DOA estimation using vector hydrophone array is also compared with that of pressure hydrophone array in rigid boundary. Finally numerical experimentatal results show its validity.
