A two-dimensional wideband direction-of-arrival estimation algorithm with acoustic vector-sensor array

A two-dimensional wideband Direction-of-Arrival (DOA) estimation algorithm with acoustic vector-sensor array is proposed, which is based on the idea of wideband focusing to solve the coherent sources problem, and the estimated DOA parameters are automatically paired. By Monte Carlo simulations, it shows that the proposed algorithm: (1) can determine the number of the sources reliably; (2) does not suffer from the performance degradation due to the same DOA parameters in the incident sources; and (3) is robust when there are array gain and phase errors.
