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.
