摘要
本文应用矢量口径积分和表面积分技术 ,给出了机载雷达罩波瓣特性的定量分析方法 ,在天线俯仰面尺度与波长相近及天线罩俯仰面曲率变化大的情况下 ,口径积分 表面积分方法比三维射线法更为精确 ,仿真计算结果与试验结果较为符合 ,证明了算法的有效性 .
In this paper,the quantitative analysis method of the effects of airborne radome on the sidelobe of antenna enclosed is presented,by means of vector aperture-integration and surface-integration(AI-SI).When the radome dimension in elevation is around λ and the wall curvature varies significantly,it is more accurate to use the AI-SI method than 3 dimension ray tracking method.The calculated simulation results show good agreement with the scaled experimental data and the validity of the algorithm has been proven.
