【摘要】 电磁兼容（EMC）性是军用设备及系统的一项重要指标, 关系到武器装备整体效能能否正常发挥。现今飞机种类繁多，安装的电子设备庞杂，机内机外电磁环境复杂、技术难度高，尤其是雷达天线及其加装配置系统的电磁兼容问题是难点中的关键。本课题就是在飞行器天线设计、安装初始阶段，通过精确的理论分析，预测天线安装位置，使安装的天线既满足飞机的气动性能要求，又能实现各自的主要战（技）术指标和天线间的电磁兼容。本文的根本理论基础是一致性几何绕射理论（UTD），它是电磁场理论中高频分析方法中最灵活最有用的方法之一。本文在深入研究这一理论的基础上，系统总结了一些典型几何构件如平板、圆柱的几何绕射解，使其更具有实用性，更加便于计算机程序处理，并给出了实际算例，多方证明了理论方法的正确性。这一工作是进行机载天线电磁兼容分析所不可或缺的一个重要部分。在文章的最后一章里，具体给出了某飞行器上单极子天线的散射分析图，从总体上给出了本文结果，起到一定参考作用。更多还原

【Abstract】 Electromagnetic compatibility (EMC) is a key standard in the military facilityand system, because it determines weather the integral part of weapon facility canwork normal. Nowadays, the electronic facility installed on various kinds of airplanesis large and complex, which make the electromagnetic environment complex and thetechnique difficult. Especially the radar antenna and the electromagnetic compatibilityof the system installed on it is the key problem in the difficulties. The exact theoryanalysis and antenna installing place prediction at the first phase of the antenna designand installation contents the requirement of not only airplane pneumatic character butalso the respective military standard and the electromagnetic compatibility betweenthe antennas in this project. The base theory of this thesis is uniform geometry theoryof diffraction, which is one of the most flexible methods of high frequency analysis inthe electromagnetic theory. On the base of deep research of this theory, the geometrydiffraction solution of some typical geometrical part such as board or column issummarized systemically, which make it more practical and easy to compute program.The actual computing example is given to prove the correctness of this theory in manyways. This work is the unavoidable part in the airborne-antennas electromagneticcompatibility analysis. In the last chapter, the scattering pattern of the monopoleantenna installed on the certain airplane is given.更多还原
