| 摘 要： | 目的计算并分析机载短波天线激励机身表面近场的分布．方法用B样条方法进行飞机的整体计算机建模，并模拟其机载的短波天线，用时域有限差分法完成短波天线激励机身表面近场的分析计算．结果得到了位于机身表面样点的近场分布，以曲线及飞机轴向纵剖面的场分布灰度图的形式表示．结论在这种建模方法下，分析所得结果符合机载天线理论，它可为机载短波天线阻抗特性、远场方向图的研究，以及短波通信设备对其它机载电子设备干扰问题的分析提供基础及依据，这种研究对飞机的电磁兼容分析和设计有重要意义．

| Abstract: | Aim To calculate and analyze the near field distribution of ariborne short wave antenna. Methods B-spline method was used to get the mathermatital model of a Boeing 707320Baircraft and simulate its short wave antenna . FDTD (finite-difference time-domain) method are ed tO complete the calculation and analysis. Results The near field distributions on aircraft's surface were obtained, the curve and gray figures of the normalized near field value were shown. Conclusion These modeling and calculating methods can provide data foraircraft's EMC analysis and design. |
