摘　　要：旨在以曲面共形天线布阵改善阵列对载体的动力学影响,提升载体的空间利用率,解决平面阵中波束控制约束、雷达散射截面积较大及角度覆盖等限制,研究了共形干涉仪布阵构型及其约束,利用平面与曲面之间的映射关系,确定了易于安装的阵元位置,采取了二维复合搜索方式寻找最佳模糊数。同时由于曲面共形的复杂性,天线单元方向图的不一致性,修正了天线单元间的初始相位差及偏心偏轴对于测量结果的影响,通过给出设计图及相应的仿真结果,表明所提布阵设计结合相应的测向方法,可以达到有效测向的同时,满足空气动力学要求苛刻或隐身方面有需求的应用场景,弥补了传统平面阵存在的不足之处。In order to improve the dynamic effect of the array on the carrier and the spatial utilization of the carrier by arranging a curved conformal antenna array,and solve the limitations such as beam control constraints,large radar cross section and angular coverage in a planar array,this paper studies the configuration and constraints of conformal interferometer arrays,uses the mapping relationship between the plane and the curved surface to determine the array position which is easy to be installed,and adopts a two-dimensional composite search method to find the optimal fuzzy number.Meanwhile,due to the complexity of the curved surface conformal configuration and the inconsistency of the antenna element's directional pattern,the initial phase difference among the antenna elements and the effect of eccentric axis deviation on the measurement results have been corrected.By providing the design diagram and corresponding simulation results,it is shown that the proposed array design combined with corresponding direction finding methods can achieve effective direction finding while meeting the application scenarios with stringent aerodynamic requirements or stealth requirements,which makes up for the shortcomings of traditional planar arrays.
