UCA-ESPRIT Algorithm for 2-D Angle Estimation

摘要

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