基于矢量传感器阵列空间谱DOA估计

DOA estimation based on spatial spectra of acoustic vector sensor array

研究了两种典型的空间谱估计方法在水声矢量传感器阵列定向中的应用,推导了空间谱的解析表达式.与标量传感器阵相比,基于矢量传感器阵列空间谱的DOA估计方法对阵列定向性能有明显改善.数值算例证明了这一点.

The application of Bartlett and Capon spatial spectra estimation methods is expanded to vector sensor array. Expressions of the spatial spectra based on acoustic vector sensor array are derived. Compared with the expressions based on traditional pressure sensor array, improvements are attained by using acoustic vector sensor array for directionofarrival(DOA) estimation. The numeric examples have proven the results.
