摘　　要：文章针对九通道干涉仪测向系统中测向方法,解相位模糊和通道一致性的校正过程这些主要技术难点,详细给出了一套实用并且实时的处理算法,提出将互相关方法,立体基线法和最小二乘法相结合的整个测向算法流程,并且做了通道校正前后的方向角误差比较,仿真结果证明了本文测向系统算法的可行性和在工程应用中的价值。This paper firstly analyses direction finding ,phase ambiguity and channel disorder with nine units circular antenna array interferometers. Then it gives a set of applied and real-time processing algorithm against them. This algorithm puts of cross corre- lation, tridimensional base lines and least squares method together to solute the whole system direction finding error. Lastly, it＇s important to make a general emulation based on our algorithm ,and the results indicate that the way is great in project applications.
