| 摘 要: 针对阵列天线的布阵问题，设计了一种阵列天线仿真系统，实现了阵列天线设计的可视化操作。通过设置阵元数、波长、阵元间距等天线相关参数，系统能够实现直线、平面、圆形和圆柱四类阵列天线的仿真分析。针对四类阵列天线稀疏布阵问题，系统采用遗传算法，对稀疏阵列天线的方向图特性进行研究。通过系统的仿真，用户可以直观地观察阵列天线方向图的变化，从而调整相关参数实现阵列天线方向图的优化设计。该仿真系统具有操作简单、页面简洁、交互性强等特点，能够支持和辅助用户分析与设计阵列天线。 |

| Abstract: Aiming at the arrangement problem of array antenna, this paper proposes an array antenna simulation system that realizes the visual operation of array antenna design. By setting the antenna-related parameters such as the number of array elements, wavelength, and array element spacing, the proposed system can realize the simulation analysis of four types of array antennas: straight line, plane, circle and cylinder. As to the sparse array problem of four kinds of array antennas, the pattern characteristics of sparse array antennas are studied by using genetic algorithm. Through system simulation, users can intuitively observe the changes of array antenna pattern, so as to adjust relevant parameters and realize the optimal design of array antenna pattern. The simulation system has the characteristics of simple operation, concise page, strong interactivity, which can support and assist users to analyze and design the array antenna. |
