Title Pattern Analysis and Synthesis of the Antennas Array
Abstract The research works are made with scientific projects. The design methods of the conical conformal array and the beam scanning of the array antennas used in special field are discussed in this dissertation. In the dissertation, the major works can be pided into three parts: the study of the conical conformal arrays with axial main beam , the beam scanning of the conical conformal arrays are proposed in the second part. The author’s major contributions are outlined as follow: 1. In the study of conical conformal arrays, in attempt to axially orient the main beam of the array, a projection principle is proposed to manage the polarization orientation of each element. Then, a 48-element and a 96-element conical conformal array is analyzed via HFSS to validate the efficiency of the proposed method. In addition. 2. Matlab procedures are used to achieve the beam scanning of the conical conformal arrays, and the method was verified by comparing with HFSS. Lastly, semi- fed optimization method are proposed and validated .

形阵列天线、锥形阵列天线的各个单元之间的互耦效应。Pasala 和 Morton[4,5]对锥形共形阵天线进行了深入的探讨，优化综合了共形阵天线的波束扫描方向图。Guy[6]采用个十字交叉振子作为天线单元，设计了 2300 元锥形共形阵天线，并采用连续投影法综合阵列和波束和差波束方向图。 然而，上述文献中所公开的锥台或者锥形共形阵天线，其辐射波束的指向在俯仰面都无法到达轴线方向，这对于导弹的目标跟踪能力极为不利，源]自{优尔·~论\文}网·www.youerw.com/ 为了解决导弹精密跟踪问题，就必须解决锥台共形阵列天线的轴向辐射波束实现[7]。
