A Fast Sparse Covariance-Based Fitting Method for DOA Estimation via Non-Negative Least Squares
ICASSP 2020accepted
A fast sparse covariance-based fitting algorithm with the non-negative least squares (NNLS) form is proposed for the direction of arrival (DOA) estimation. The Khatri-Rao product of the array manifold of the uniform linear arrays is utilized to achieve the dimension reducing transformation after vec…
