Artificial signals possess some certain chronological property-the cyclostationarity, with which the traditional DOA estimation can rarely reach the desired precision, or completely turns to be of no avail. Designated for removing the defect, this paper applies the Cyclic-Music algorithm to the MIMO radar's DOA estimation and verifies its effectiveness. Simulations show that the precision of MIMO...
Source localization is an important problem in array signal processing and it is used to estimate the direction of arrival (DOA) of multiple sources. In this paper, we present a four-order cumulant based ESPRIT like method for passive localization of near-field narrowband non-Gaussian sources using a centrosymmetric cross array. The proposed method uses the multiple-rotational invariance among certain...
A method for 2-dimension DOA source parameter estimation based on MSWF (multistage Wiener filters) is proposed in this paper contrasted to the computational complexity increasing in MUSIC algorithm. The presented method does not require the formation of the covariance matrix and its eigen decomposition or singular value decomposition, and it can estimate azimuths, elevations and the numbers of the...
A method for uniform circular array (UCA) sources parameters and sources number estimation based on multistage Wiener filters (MSWF) is proposed in this paper. The method proposed in this paper does not require the formation of the covariance matrix and its eigendecomposition or singular value decomposition, and relies on the forward recursion characteristic of MSWF. It can estimate azimuths, elevations...
