摘    要:从阵列入射信号具有统计独立和空域独立这两个方面出发,利用ICA和MUSIC算法相结合,进行未知源信号数目的DOA估计,在算法迭代的过程中,得到源信号数目的同时也得到了源信号的DOA.通过仿真实验表明,该算法能对未知源数目的信号进行DOA估计,并且在低信噪比和存在弱信号的情况下仍然有效.

关 键 词:独立分量分析(ICA)  MUSIC  波达方向(DoA)估计  源数目估计

Abstract:Incident signals with characteristics of Statistically independent and spatial independent, in this paper , the combination of ICA and MUSIC Algorithm be used to estimate DOA of the number of unknown source signals. In the algorithm iterative process to obtain the number of source signals and the source signal of DOA. Thesimulation results show the proposed algorithm can estimate the DOA of singnals under / unknown source number, and in the case of low signal-to-noise ratio and the presence of a weak signal is still valid.
Keywords:independent component analysis (ICA)  MUSIC  direction-of-arrival estimation  source number stimation
