Source number detection in spatial correlated color noise using the canonical correlation coefficients

The accurate estimation of source number detection may be very essential to high-resolution array processing. However, the traditional algorithms are sensitive to different noise fields. To overcome the drawback, this paper addresses a novel effective accurate detection algorithm by using the canonical correlation coefficients of the joint covariance matrix. Compared with the traditional algorithms, the presented algorithm has better performance and lower complexity.The simulation results demonstrate the effectiveness of the proposed algorithm.
