摘要
采用一致性几何绕射理论分析了某型航空飞行器机体对其上安装的通讯线天线辐射方向图的影响,给出了航空飞行器散射模型建立的原则和方法,对安装在飞机表面的通信线天线阴影区散射场计算公式进行了详细的分析推导,设计了机载通信线天线辐射方向图计算软件,可快速准确计算机载天线辐射方向图.以通信常用单极子天线为例,计算了机体表面不同安装位置线天线受载机影响辐射方向图,该结果对机载天线安装位置优化有指导意义.
The Uniform Geometrical Theory of Diffraction （UTD） is presented to analyze an airborne antenna radiation pattern. The method for setting the scatter model of an aircraft is put forward. The computation formula for the radiation field of the airborne communication antenna in the shadow region is carefully investigated. The computer program of the radiation pattern of an airborne communication antenna is designed. The airborne antenna radiation pattern can be computed rapidly and accurately. Taking the dipole antenna as an example, the radiation pattern of the antenna in different locations on the airborne surface is computed. The results presented in this paper can be used to study the optimization of the airborne antenna disposition.
