High-resolution subspace method for DOA estimation
Improved subspace method as a way of toughness. Subspace perturbation analysis to the evaluation and control of the division of Unitary Space Vector choice is important. Therefore, it is subspace of the important issues. ・ 2lO ・ Harbin Shipbuilding Engineering Institute of the first volume reference l2 lScinnidtR. MultipleemitterlocationandSignalParameterestimation.
