摘要
基于均匀圆阵(UCA),提出了一种垂直平滑解相干算法。利用在两个垂直的方向上平移,得到多个平移后的协方差矩阵。对其进行平均,将协方差矩阵的秩恢复为满秩,实现解相干,完成对相干信号的DOA估计。仿真结果表明,该方法具有较好的可行性。
This paper proposes a new perpendicular translation algorithm based on Uniform Circular Array （UCA）. Firstly, shifting the array at two perpendicular directions, more covariance matrices are generated. By averaging the previous results, a new covariance matrix is obtained. It is a full rank matrix.Then the Direction of Arrival （DOA） of coherent signals is estimated. The simulation results shows that this method was feasible.
