Covariance beamforming, covariance matrix tapers and matrix beamforming are related
Ju Li, Petre Stoica, Tarik Yardibi · Electronics Letters · 2008
It is shown that the covariance beamforming, covariance matrix tapers and matrix beamforming approaches, which were considered separately from one another in the previous array processing literature, are in fact related. The relationships between them in terms of both generality and design procedures are clarified.
