Abstract

In this paper, we developed a novel version of PM-Root-MUSIC algorithm for uniform circular array (UCA) in order to avoid the performance degradation of DOA estimation when the number of elements in UCA is small. Based on the manifold separation technique (MST) and propagator method (PM), a beamspace DOA estimation algorithm for UCA was proposed. This method requires no eigen-decomposition calculation, therefore reduce the computational load significantly, and provide close to CRB performance even applied to UCA with limited number of elements.
