摘　　要：针对传统算法中多维搜和索运算量大的问题,首先结合ESPRIT和纯方位估计方法,提出了一种基于声矢量传感器阵列的近场源两步定位算法;然后,利用常规的阵列流形矩阵,结合矢量传感器的ESPRIT定位算法,实现了单传感器的方位角和俯仰角的估计;最后,通过最小二乘估计的方法实现了声源的定位。随后的仿真结果证明了该方法的有效性。In order to solve the problem of huge calculation amount in the traditional algorithm,firstly a two-step localization algorithm for near field source based on the acoustic vector hydrophone is proposed by combining ESPRIT and bearing-only location.By exploiting the regular array manifold matrix,the ESPRIT solution of AVS array is implemented to estimate the azimuths and elevations of sources at each sensor.Finally,the locations of sources are estimated by the least square（LS）method.Simulation results are provided to demonstrate the performance of the proposed method.
