High-resolution direction finding using eigendecomposition based estimators and joint estimation strategy
Abstract
A new direction finding method is proposed which can greatly improve the performance of the original MUSIC and minimum-norm methods by reducing the SNR threshold. This method is based on a very simple joint estimation strategy and uses the MUSIC spectral estimator and all generalized minimum-norm estimators simultaneously.
