| 摘 要： | 论述了双频共面单脉冲天线的设计方法。天线口径较小时,馈源的遮挡口径相对较大,这对天线的性能影响很大,选择口径较小的双频馈源是实现双频共面的关键。天线低频段馈源采用4喇叭单脉冲形式,高频段馈源采用单口多模单脉冲喇叭,通过各自的馈电网络实现单脉冲功能。天线采用卡塞格伦形式,通过对天线和馈源的优化设计,可实现天线双频段工作性能,实测结果与计算结果基本吻合。

| Abstract: | The design method of monopolse common reflector dual frequency antenna is presented.When the diameter of an antenna is relative small,the blockage of feed is larger,this will influence the performance of the antenna,the major factor is how to select smaller diameter of dual frequency feed that used to common reflector antenna.The feed of lower band consists of four horns to perform monopulse channels.The higher band feed is a monopluse multimode horn.The feed networks of dual bend can finish the monopulse f... |
