推导了基于水声矢量传感器阵的Bartlett 和Capon 空间谱的解析表达式,并与标量传感器阵的空间谱相比较,分析了基于矢量传感器阵的两种DOA 估计方法对阵列定向性能的改善,并给出了数字算例。
关键词:波达方向;空间谱;矢量传感器
Abstract :Expressions of the Bartlett and Capon spatial spectra based on acoustic vector sensor array are derived. Compared with the expressions based on traditional pressure sensor array , improvements attainted by using acoustic vector sensor array for direction2of2arrival (DOA) estimation are discussed.
Key words :direction - of - arrival ; spatial spectrum; vector sensor
