Abstract :
According to the Root-MUSIC algorithm for acoustic pressure sensor array, we put forward a new Root-MUSIC algorithm with real-valued eigendecomposition for acoustic vector sensor array,. By way of recomposing the covariance matrix of vector sensor array and selecting appropriate lead orientation vector via spatial spectrum of array signal, we successfully evaluate the Direction of Arriva (DOA). Theory analysis and simulation experiment of an uniform line array show the performance of the new Root-MUSIC algorithm with real-valued eigendecomposition for acoustic vector sensor is better than the traditional Root-MUSIC algorithm with real-valued eigendecomposition in low SNR and few snapshots, and the calculations of new algorithm is small than the traditional MUSIC algorithm.
