Abstract

In the electronic warfare reconnaissance system, interferometer direction finding has been widely used with its advantages of simple structure, high accuracy and high sensitivity. However, it also suffers from the phase difference ambiguity problem, so the accuracy of interferometer direction finding largely depends on the correct rate of phase ambiguity resolution. This paper proposed an adaptive ambiguity resolution algorithm for phase error equivalence space, which can adaptively accomplish the resolution of phase ambiguity with arbitrary baseline number and arbitrary baseline ratio, and the effectiveness of this algorithm was validated through engineering practice and simulation examples.
