Aiming at the situation of two coherent sources, their bearings are estimated of high resolution by single acoustic vector-hydrophone. The pressure and particle-velocity channels of single acoustic vector-hydrophone can be considered as an array at one point with special spatial directivity. The reception model of two coherent sources is gained and the signal covariance matrix of single acoustic vector-hydrophone is decorrelated by the method of phasic smoothing, then the performances of different high-resolution algorithms are compared. The computer simulation indicates that a single vector hydrophone can realize two coherent sources DOA estimating and the method of vector optimization robust beamforming (VORB) gives the best DOA estimating result.
