摘　　要：综合利用圆阵和正交线阵混合天线阵的特性,对全局模糊值搜索优化方法进行了深入研究。提出了一种基于圆阵解模糊引导正交线阵的干涉仪快速解模糊算法,使高频辐射源信号相位解模糊搜索次数降低至传统方法的1.14%。同时,针对圆阵的不同阵元个数、直径及阵列布局等方面进行了仿真分析。结果表明,增加圆阵阵元数、降低频率、优化布局均能显著提升相位解模糊概率。七圆阵与十字阵组合在0.8~12 GHz范围内实现了优于99%的解模糊概率,为实际工程应用提供了有价值的参考。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.
