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.
