传统源数估计方法要求传感器数大于或等于源数 ,而盲信号很难满足这个条件 ,为此 ,提出了

一种新的源数估计方法。 该方法在传感器数与源数关系不明确的情况下 ,仅根据观测信号的功率谱密

度函数的比值即可对源数作出估计。 通过理论分析、仿真和实验 ,证明了该方法的有效性 。-Traditional source number estimation method for sensor number is greater than or equal to the source, and fanaticism, it is difficult to meet this condition, therefore, is proposed

A new kind of source number estimation method.This method in the relationship between the source and sensor under the condition of not clear, only according to the observation signal power spectral density

The ratio of degree function can make an estimate of the source number.Through theoretical analysis, simulation and experiment, proved the effectiveness of the proposed method.
