Enhanced off-grid DOA estimation by corrected power Bayesian inference using difference coarray

Sparse Bayesian inference for on-grid direction-of-arrival (DOA) estimation using difference coarray was investigated in the authors’ previous work to estimate more signal sources than the number of physical antenna elements. Sparse Bayesian inference is derived based on a linear inverse model and t...
