title = "Spatial coherence of sub-arrays in spherically isotropic noise",
abstract = "A Close-form solution of spatial coherence for collinear sub-arrays in spherically isotropic noise is proposed in this paper. By utilizing beamforming techniques, sub-array outputs can be expressed in a combination of the fixed weight vector, the steering vector and the frequency domain sequence received by the first sensor. Then the formulations of the power spectrum density and cross-power spectrum density of two sub-arrays will be simplified to those with summations instead of integrals, which can be analytically computed. It is shown that the half power beam width of sub-array determines the amplitude of spatial coherence, and the angle between the beam steering direction and the line across two acoustical centers of sub-arrays affects the frequency of curve's fluctuation. Numerical simulations demonstrated the accuracy of the analytical solution and the validity of the related theoretical analyses.",
