| 摘 要： | 为了研究机载多天线系统的电磁兼容特性,针对天线系统性能优化问题,分析各天线之间的干扰程度和引起天线间干扰的因素得到提高系统性能的方法。分别建立飞机平台的简化模型和三维实体模型对天线耦合度进行仿真,采用遗传算法着重分析在固定工作频率下天线的位置对耦合度的影响,并用时域有限差分算法进行仿真验证,分析所得结果吻合。模型中综合考虑了多根天线的影响,最终获得待挂载天线的最佳位置,为多天线系统设计提供了依据。

| Abstract: | To research the electromagnetic compatibility of airborne multi-antenna system,we can improve the performance of the system by analysing the interference among the antennas and the influencing factors.Both simple model and accurate 3D model of the plane were constructed to simulate the coupling degree between the antennas.Genetic algorithm was introduced to analyse how the position of the antenna influences the coupling degree while working at the fixed frequency.The result from the simulation by FDTD algor... |
