基于均匀圆阵的二维ESPRIT算法研究

在深入研究均匀圆阵扩展阵列流形的基础上，针对某些均匀圆阵的扩展阵列中含有旋转不变性的子阵列组以及中心对称性质，提出了2种基于均匀圆阵的二维ESPRIT算法，第一种算法减少了一次奇异值分解，第二种算法避免了参数配对。仿真结果验证了算法的正确性和有效性，并且在高斯色噪声条件下，其测向性能均优于MUSIC算法和最大似然算法。

2-D ESPRIT algorithm research based on uniform circular array

Based on the depth research on extension array manifold of uniform circular, for some uniform circular arrays which had subarrays with the nature of rotational invariance and had the nature of central symmetry two ESPRIT algorithms were presented, the fast algorithm reduced one time of SVD, the second algorithm avoided parameter pairs. The computer simulation confirms the validity and the accuracy of the algorithms, moreover their performances are better than MUSIC and ML algorithm when the noise is colored Gaussian noise.
