  Abstract

In this paper, a super resolution 2-D DOA estimation method of UCA based on eigen-space transformation is proposed. UCA is widely used in various areas because it has the advantage of estimating 2-D DOA, azimuth and elevation, respectively. The proposed method is performed by using the iterative beamformer that transforms eigen-space of received signal at UCA. The proposed method has lower computational complexity and better performance of DOA estimation than conventional methods such as MVDR, MUSIC, and UCA-ESPRIT. The performances of proposed method are verified by computer simulation.
