英文摘要	The ocean ambient noise contains abundant information of the ocean environment, so it is necessary to study its characteristics. As a function of frequency, geographical location and time, the directivity of ambient noise is an important characteristic of ocean ambient noise and an important factor affecting the gain of hydrophone array. A single vector hydrophone can simultaneously measure the acoustic pressure and particle velocity at the same point, and can be considered as a scalar array. In this paper, a method using minimum variance distortionless response (MVDR) beamforming for ocean ambient noise directivity analysis is studied, and the measured data of a shallow ocean low frequency ambient noise received by a single vector hydrophone is processed and analyzed. The results can be used to understand the ocean ambient noise characteristics of the area.
