摘　　要：介绍了干涉仪测向的基本原理,并给出了其在N元均匀圆阵模型中的具体算法。利用基线组聚类分析法,并结合幅度比较,给出了N=6和N=8的干涉仪测向MATLAB仿真结果。仿真结果显示所采用的测向算法具有较好的解模糊稳健性和容错能力,可以为无源定位研究提供有益的参考。This paper introduces the basic theory of direction finding（DF） of interferometer,and gives the detailed algorithm of its application to N-unit even circular array model,using the baseline group clustering analysis method,combining with the amplitude comparison,presents MATLAB simulation results when N=6 and N=8.The simulation results show that the adopted DF algorithm has better stabilization in soluting ambiguity and fault-tolerance capability,which can offer the favorable reference for passive location study.
