摘要
波达方向(DOA)估计的基本问题就是确定同时处在空间某一区域内多个感兴趣的信号的空间位置(即各个信号到达阵列参考阵元的方位角,简称波达方向)。提取波达方向信息是智能天线技术中的关键任务之一。文中主要研究波达方向估计算法中的延迟-相加法、Capon最小方差法、常规MUSIC算法和改进型MUSIC算法。通过仿真,比较了不同波达方向估计算法的性能。
The basic question of DOA estimation is to confirm the special positions of the interested signal in a certain area. （Namely, the azimuth angle of each signal arriving reference array antennas, DOA for short）.Acquiring DOA information is one of the key techniques in smart antennas technology. This paper focuses on the research of delay-addition algorithm, capon algorithm, conventional MUSIC algorithm and modified MUSIC algorithm.The paper compares the performances of various DOA algorithms through the simulation.
