| 摘 要： | 现代电子战要求在飞机上安装越来越多的雷达天线，由于金属机身的存在，雷达天线的辐射受到机身的影响，为了减少这种影响，在飞机研制，改型设计中，需要计算天线在飞机附近辐射场的分布，从而选择适当的天线安装装置。本文采用一致性几何绕射理论（ＵＴＤ），讨论在机身上安装高频振子天线时，飞机滚动面内的辐射场计算模型及计算结果。

| Abstract: | Modern electronic warfare requires more and more air borne radars and antennas bei ng fixed on aircraft.Radiation of air borne antenna will be effected by the metal body of aircrdft.In order to solve this Problem or reduca the effection,near field pattern sho uld be calculated during the designing stage of aircraft, thus to select the proper locat ion of the antenna.In this article, UTD is applied to discuss the calculation-model.The calculation results are given at last. |
