Abstract :
It is demonstrated that signal wavefronts may be resolved by eigenvector rotation. This technique relies on the source eigenvectors rather than the noise eigenvectors. It is shown that the technique is easy to perform numerically and that the resolution is superior to that obtained from the MUSIC algorithm.
