| 摘 要： | 针对单通道测向方法普遍存在运算量大或测向精度低的缺点,提出圆阵单通道顺序采样二维超分辨测向的算法。算法将圆阵多次轮巡所得的顺序采样数据等效为每个阵元同时采样并进行多次快拍的数据,并通过构建单通道圆阵特有的含有开关切换时间间隔的导向矢量,采用等效加权的MUSIC算法,实现对信号的测向。计算机仿真证明:其具有较高的测向精度,逼近了多通道测向算法。

| Abstract: | Aiming at the disadvantages of large amount of computation and low direction-finding accuracy of some direction finding algorithms based on single-channel,a two-dimensional direction finding algorithm based on single-channel sequential sampling with circular array was put forward in this paper.The method took the equivalence of the sampled data obtained by the antennas of circular array to the sampled data of every antenna synchronously,and then signals' DOA was estimated by equivalent weighted MUSIC algori... |
