Abstract :
In this paper, a novel method for the spatial-temporal spectral estimation of multiple narrowband plane waves is developed based on the multistage Wiener filter (MSWF). The proposed method does not apply the estimation of covariance matrix and its eigendecomposition, therefore, its computational complexity is low. The numerical examples are used to demonstrate the performance of proposed method
