摘要
波达方向估计是利用天线阵元对空间信源的来波方向进行估计。在二维平面,将来波方向和阵列法线的夹角定义为波达方向,由此定义阵列信号处理的基本数学模型。采用非参数化方法估计波达方向,包括Bartlett、Capon、MUSIC等方法。对其仿真表明,在估计精确度方面MUSIC法最好,Capon法次之,Bartlett法最差。
DOA （direction of arrival） estimation is realized by using antenna array to estimate the arrival direction of space signal source. In 2-dimension surface, the included angle between arrival direction and array line is defined as DOA direction. According to this, the basic math model of array signal processing is also defined. The non-parameter method used for evaluating the DOA includes Bartlett, Capon, and MUSIC. The simulation proves that the MUSIC is the best in evaluation accuracy, Capon is the second, and the Bartlett is the worst.
