Abstract: Acoustic energy flux of anisotropic ocean ambient noise is studied,which is caused by horizontally nonuniform distributed noise sources.A mixed model of non-uniform distributed noise sources is established.Acoustic energy flux of anisotropic ocean ambient noise is analyzed and calculated based on this noise model.The numerical results show that the ambient noise field caused by non-uniform distributed noise sources has obvious nonzero horizontal acoustic energy flux;the acoustic energy flux varies distinctively at different receiver position;its magnitude and direction depend on the synthetic effects of the different parts of noise sources.The changes of the normalized correlation coefficients with the receiver distance between the pressure and horizontal particle velocity at two different receivers,and horizontal particle velocities at two different receivers have been studied,with high correlation coefficients,which provides theoretical basis for analyzing the performance of target detection technology using underwater vector field.
