低副瓣机载雷达罩中维修孔对雷达天线副瓣的影响十分复杂 ,迫切需要理论分析 ,文中建立了维修孔的数学模型 ,采用矩量法对维修孔及孔盖中金属和介质附件中被激励的传导电流和感应电流进行了数值计算 ,得到了维修孔对天线副瓣影响的数值 ,理论分析与测试结果符合较好

The effects of access panel in airborne radome upon the sidelobe of antenna enclosed is very complex . It is urgent to obtain theoretical analysis. In this paper ,a theoretical model is given and the conduct current and induced current in the dielectric and conduct attachments are computed by moment method .The numerical result of pattern of scattering caused by access panel are obtained with good accuracy compared with the measurement.
