A New High Resolution and Stability Estimation Method for DOA
Dengshan Huang · Jisuanji fangzhen · 2009
A new dirrection of array estimation method is proposed for uniform linear array in this paper.Eigenvectors corresponding to the maximum eigenvalues of the correlation matrix are arranged as an unsymmetrical matrix(V)by definite rule and the signal-subspace and the orthogonal subspace can be got from the sigular value decomposition of V.Because of the special property of V,the angle of sources can be resolved by the new method.The common DOA estimation approch MUSIC needs high SNR gate and the common decorrelate menthod FBSS can't use the message of the full correlation matrix sufficiently,and the proposed method can overcome these limitations.Lots of simulation results demonstrate the effectiveness and efficiency of the proposed method
