摘要 提出一种基于声矢量传感器阵的宽带源二维波达方向估计算法,在宽带相干源条件下实现了二维波达方向估计参数的自动配对。克服了通常声矢量传感器阵波达方向估计中存在的谱峰搜索和参数配对问题。分析表明:该算法能够可靠判定目标源的个数,具有较高的估计精度;不受目标波达方向角度间存在兼并(入射源含有相同的方位角或俯仰角)的影响;当存在阵列误差时,算法的稳健性好。 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.
