However. The effective aperture of array will be reduced because the ability of decorrelation was gain based on sacrificing the effective number of arrays, and, in the circumstance of lower SNR(signal-noise-ratio) , the estimation performance is deteriorated.
对相干信号源的DOA估计具有理想的性能,其计算量小,便于实现,但它是通过牺牲阵列有效阵元数来换取解相干能力的,阵列孔径有一定的损失,且在低信噪比条件下算法性能较差。
