波束空间MUSIC的色噪声免疫性
首发时间:2007-12-17
摘要:比较了高斯色噪声条件下阵元空间和波束空间波达方向估计二阶、四阶累积量多重信号分类法(MUSIC)的噪声敏感性能,定性研究了波束空间变换波瓣宽度对色噪声抑制性能的影响;还比较了非高斯色噪声条件下阵元空间和波束空间辅助阵元累积量MUSIC的噪声免疫性。结果表明,波束空间方法在变换波瓣较窄的情况下可获得优于阵元空间方法的色噪声抑制性能。

Immunity of Beamspace-MUSIC to Spatially-Colored Noise
Abstract:The sensitivity of element-space and beam-space with second- and fourth-order cumulant multiple signal classification (MUSIC) algorithms to Gaussian colored noise are compared. The effect of beam pattern main-lobe width on the performance of beamspace MUSIC is examined. The superiority of beamspace transformation in the auxiliary-element method is also investigated. It is shown that the beam-space methods have stronger colored noise immunities than their element-space counterparts, given that the beam pattern main-lobe is reasonably narrow.
