Fast ambiguity resolution method based on hybrid array interferometer
The characteristics of a hybrid antenna array combining a circular array and an orthogonal linear ar-ray are comprehensively utilized,and an in-depth study on global ambiguity value search optimization method is conducted.A fast interferometer ambiguity resolution algorithm based on circular array ambiguity resolution guid-ing the orthogonal linear array is proposed.The number of phase ambiguity resolution searches for high-frequency radiation source signals is reduced to 1.14%of that of traditional methods.Simultaneously,simulations and analy-ses are conducted regarding different aspects of the circular array,such as the number of elements,diameter,and array layout.Increasing the number of circular array elements,reducing frequency,and optimizing the layout can significantly improve the probability of phase ambiguity resolution.The seven-circle array combined with a cross array achieves an ambiguity resolution probability exceeding 99%in the 0.8～12 GHz range,providing valuable references for practical engineering applications.
