| 摘 要： | 通过分析圆阵阵列流形,提出一种新的圆阵二维谱估计模型,可以直接应用MUSIC算法进行二维DOA估计,从而避免了对圆阵输出信号进行模式激励.应用此模型仿真分析了均匀圆阵和均匀半圆阵的二维DOA估计性能,相比模式激励方法,减小了计算量;半圆阵与圆阵的DOA性能差别很小,但是半圆阵减少近一半的阵元数. |
| 关 键 词： | 圆阵 阵列流形 |

| Abstract: | Based on the analysis of array manifold of Circular Array(CA),a new 2-D spectrum estimation model for CA is presented in this paper,and there is no need to transform the manifold matrix of CA,so the MUSIC algorithm is directly used for the 2-D spectrum estimation of CA.The 2-D spectrum estimation parameters of UCA(Uniform Circular Array) and Semicircle Array(SCA) are analyzed by computer simulation in this model.Compared with mode excitation method,computation cost is reduced.There is little difference of e... |
