| 摘 要： | 分析了智能天线自适应算法波达方向估计（DOA）问题，在一维MUSIC算法的基础上讨论了二维六边形天线阵列的空间谱并进行了Matlab仿真实验；仿真结果表明，六边形天线阵列不仅可以判断波达方向的俯仰角而且可以判断方位角；同时讨论了DOA算法的分辨率，与一维MUSIC算法相似，二维条件下六边形天线阵列具有良好的角分辨率，可以满足非相干信号的工程要求。

| Abstract: | The paper analyzed the DOA estimation performance of MUSIC algorithm of uncorrelated signals. Success-fully applies the algorithm to the 2-dimension small satellite antenna array. Theory analyzing and software simulation are carried out. Matlab simulation shows that hexagonal antenna array can estimate both the pitch angle and azimuth angle. The resolving ratio of hexagonal array is feasible in engineer project and can comparable to that of one-dimension MUSIC algorithms. |
