wideband-DOA-estimation
- 提出了一种新的宽带DOA估计方法:频域子空间正交性测试方法(TOFS:Test of orthogonality of frequency sub- space)。该方法通过同时测试频域信号共同带宽内各频段噪声子空间与阵列流形之间的正交性来进行DOA估计。与宽带相干信号子空间方法不同,TOFS方法不需要任何初始值的预估及聚焦操作。与宽带非相干信号子空间方法也不同,TOFS方法同时测试各频段噪声子空间与阵列流形之间的正交性。本文仿真了TOFS与IMUSIC、CSSM、TOPS的性能比较。仿真结果表
DOA-by-modified--MUSIC-algorithm
- MUSIC算法能有效地估计出独立信号源的DOA,并且在模型准确的前提下,对DOA的估计可以达到任意精度 但对相干信号源和相隔比较近的小信噪比信号源,MUSIC算法就不能估计出它们的DOA了。这里通过理论推导提出了一种改进MUSIC算法,计算机仿真的结果表明了该改进MUSIC算法既能够有效地估计出独立信号源的DOA,也能有效地估计出相关信号源和相隔比较近的小信噪比信号源的DOA,从而证明了这种改进MUSIC算法的合理性。-MUSIC algorithm can estimate the DOA
