A robust algorithm for source number detection based on space-time averaging techniques
Ruiyan Du, Jinkuan Wang, Fulai Liu, Bin Wang · IET Conference Publications · 2009
A new source number detection method is proposed, in this paper. The presented method makes using of space-time averaging techniques to increase robustness for source number detection. Via the rotational invariance techniques, the number of incidence signal sources can be estimated, for multiple narrowband far-field signals impinging on a uniform linear array (ULA). Simulation results are presented verifying the efficiency of the proposed method. (3 pages)
