Abstract
Due to its low resolution the conventional beamformer (CBF) has generally been neglected in the recent literature on array processing and considerable attention devoted to the high-resolution (HR) techniques. Applying a deconvolution approach to the output of the CBF, the authors obtain a source localization procedure whose performances are comparable to those of the most efficient HR techniques. The scheme, moreover, also furnishes estimates of the source powers and comprises a test that detects the number of sources present. It can indeed be seen as a means to obtain maximum likelihood estimates (MLE) when the CBF-output is taken as the observed data.Keywords
