Superdirective beamforming based on spherical harmonic expansion on planar acoustic vector sensor arrays

The superdirective beamforming method based on spherical harmonic expansion is capable of generating a frequency-invariant three-dimensional (3D) beampattern. When applied to planar acoustic vector sensor arrays (PAVSAs), this method may yield a distorted beampattern. To rectify the issue of inaccur...
