In this paper, direction-of-arrival (DOA) estimation in the presence of non-uniform noise is investigated. To achieve high estimation accuracy, the DOA estimation problem is solved with the use of a matrix completion approach. The matrix completion via alternating projection algorithm (APA) is firstly utilized to find the noise-free covariance matrix of the signal, which is then used to find the DOA by utilizing the conventional subspace-based method. Numerical simulations are performed to verify the accuracy and effectiveness of the proposed approach.
