A Performance Analysis of the Modified 2-D MUSIC Algorithm Based on Conjugate Data Rearrangement
Zhijun Zhang, Zhibin Hou · Modern Radar · 2008
On the basis of describing the 2-D MUSIC algorithm and by reusing the conjugate data being rearranged and constructing correlation matrix,a modified 2-D MUSIC algorithm based on three orthogonal linear arrays is proposed in this paper. This modified algorithm can improve the performances of the signal DOA estimation significantly when the snapshot number is limit- ed,especially for the coherent signal.Computer simulation results show that the modified algorithm is effective and workable.
