Off-grid hydroacoustic signal orientation estimation based on interpolation and subspace fitting in coprime arrays.
This letter presents a novel approach to sparse Bayesian underwater acoustic signal direction estimation. The proposed method incorporates interpolation of the coprime array and signal subspace fitting. It addresses the limitations of the hydrophone coprime array in utilizing all array elements'...
