Abstract
Applying the eigenvector decomposition (EDM) beam-former to real data with an unknown number of sources, the proper number of eigenvectors to span the signal subspace has to be determined. The maximum correlation coefficient between the maximum likelihood (MLM) and EDM beamformer angular power spectra as a function of the number of eigenvectors is used to define a criterion. Data of a passive sonar line array demonstrate the successfull application.
