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 direction-of-arrival (DOA) estimation algorithm based on acoustic vector sensor array is proposed to realize the automatic matching of two-dimensional DOA estimation parameters under wideband coherent sources. Which overcomes the problem of spectral peak search and parameter matching existing in the direction of arrival of the normal acoustic vector sensor array. The analysis shows that the algorithm can reliably determine the number of target sources and has high estimation accuracy; it is not affected by the merger (the source contains the same azimuth or elevation angle) in the target DOA; when there is an array error The robustness of the algorithm is good.
