摘　　要：研究了两种阵列信号测向算法的性能:空间谱估计测向算法和干涉仪测向算法。基于均匀圆阵的硬件平台,两种算法均可实现测向功能,为针对不同的实现需要,着重介绍了因测向机理的不同在多种性能方面呈现出的差异。以五元圆阵为例,分别实现干涉仪和空间谱估计测向的仿真实验。仿真结果表明空间谱估计算法在低信噪比情况下测向精度优于干涉仪测向,而后者在测向耗时方面要远优于前者。There are two algorithms for radio direction finding： spatial spectrum estimation and phase interferometer which have been compared in this paper.In the uniform circular array,two methods with totally different theories can both get Direction-Of-Arrival（DOA）.they present distinct advantage and disadvantage in different using.In this article,the two algorithms based on five antenna array are analyzed.The results of simulation demonstrated that the spatial spectrum can get higher precision than phase interferometer in the low SNR,while the latter one uses less time than the former.
