Dengshan Huang · Information Security and Communications Privacy · 2009
Aiming of the obviously descending capability of matrix reconstruct in low SNR and small difference of angle,a new array estimation method with high resolution and stability based on uniform linear array is proposed in this paper.This algorithm realizes some improvement in the re-arranged mode of maximum eigenvalue of the correlation matrix.Due to the characteristic of the newly constructed matrix,the capability of estimating concerned signal and the precision of DOA estimation are greatly improved.The simulation results have proved the effectiveness and efficiency of the proposed method.
