摘要 当天线尺寸与波长相近时 ,三维射线方法失效。本文应用口径积分技术 ,分析了小型机载雷达罩对罩内喇叭天线辐射特性的影响。采用口径积分 -表面积分方法分析发现 ,喇叭天线加流线型罩后 ,增益增加 ,波瓣出现起伏 。 When the horn dimension enclosed in radome is around λ , the 3-dimension ray tracking method is no longer valid . In this paper , the analysis on characteristics of small airborne radome is present , by means of aperture integration technique . It is found from the analysis results with the aperture-integration and surface-integration method that the gain of horn increases and the pattern undulates . The prediction has been proven by the experiment.
