本文提出了一种适合于均匀圆阵的高分辨阵列测向算法，该算法首先将圆阵由阵元空间转化至模式空间，然后通过引入噪声流形阵对最大似然测向算法进行改进，形成了非多维搜索优化的圆阵噪声流形算法．计算机模拟结果显示，该算法不仅计算量小，而且具有较强的解相干信源的能力
In this paper, a high-resolution array-based DF algorithm is proposed, which is suitable for uniform circular array. Firstly, the circular array is converted from space element array to pattern space, and then the maximum likelihood direction finding algorithm is improved by introducing a noise manifold. A non-multidimensional search optimization circular array noise manifold algorithm is formed. Computer simulation results show that the proposed algorithm not only has less computational complexity but also has stronger ability to solve coherent sources
