UCA-ESPRIT algorithm for 2-D angle estimation

The uniform circular array UCA-ESPRIT algorithm for 2-D angle estimation is researched in this paper. The element space manifold is transformed into the beamspace manifold via phase mode excitation for UCA. The eigenstructure-based estimation algorithm UCA-ESPRIT can be employed in beamspace. The UCA-ESPRIT algorithm provides automatically paired source azimuth and elevation angle estimates. By exploiting the centro-Hermitian property of the beamspace manifold, forward-backward averaging can be operated in a coherent signal environment. Results of simulation are presented
