Abstract :
The performance of the enhanced minimum variance (EMV) spatial spectrum estimator is studied. Expressions are presented fur the variance and bias of direction of arrival estimators based on general functions of the covariance matrix, and these expressions are then used to study the EMV estimator. Finite data effects and random perturbations on the ideal modeling assumptions are studied separately
