Abstract :
Based on uniform circular arrays (UCAs), a robust estimation of azimuth-elevation for some sources is proposed. Because of exploiting directly array manifold, the proposed algorithm is less in the computational load. The removal of cyclic ambiguous is presented, so that the accurate estimation of azimuth-elevation is obtained. Numerical results show the proposed algorithm is robust to amplitude and phase perturbation of sensor
