2-D DOA Estimates for Coherent Source Based on Weighted Subspace Fitting
He Ming · Modern Radar · 2001
For the purpose of estimating 2 D DOA of uniform circular array(UCA), phase mode excitation based UCA beamforming is employed to obtain real valued beamspace manifold. We researched the subspace eigenvalue decomposition and weighted subspace fitting techniques in the beamspace. The computer simulations indicated that the weighted subspace fitting technique in the beamspace possessed a significant advance of 2 D estimation for coherent sources.
