A method for determining the number of signals based on modified K-means clustering

摘要：

Determining the number of signals impinging on an array of sensors is one of the hot and important problems in array processing field. Research on estimation method which is available in colored noise field has important theoretical and practical meaning. A new method is proposed based on K-means clustering algorithm, we construct a distinguishing criteria in reason according to the difference between the signal and noise eigenvalues, and then the signal and noise eigenvalues are classified into two kinds using K-means clustering method. The method is valid in colored noise field. Computer simulation results and the available measured data confirmation prove the effective performance of the method.
