Direction of arrival estimation in sparse arrays in the presence of unknown colored block-correlated noise fields]
Abstract
We address the problem of maximum likelihood (ML) direction-of-arrival (DOA) estimation in unknown spatially correlated noise fields using sensor arrays composed of multiple subarrays on a sparse grid. In such arrays, the noise covariance matrix has the block-diagonal structure which enables to reduce substantially the number of nuisance noise parameters and ensure the identifiability of the underlying DOA estimation problem. A new …
