摘要:

为满足测量船未来深空探测测控任务的需求,设计了三频段合用的波束波导天线。通过计算各频段在4种情况下的波束不一致及增益损失,分析了多频同时工作时电轴不一致对天线性能的影响,提出了天线尽量跟踪在高频段的使用建议,对实际应用具有极大意义。

Abstract:

Shipborne tri-band beam waveguide antenna is designed to satisfy the need of de ep-space TT&C tasks. By computing beam inconsistency and gain loss for each band in four different conditions,the impact of electrical axis inconsiste ncy on performance is analyzed in simultaneous operation at S/X/Ka-band. Sugges tions for high frequency tracking are given,which is meaningful for practical ap plications.

Key words: TT&C ship tri-band antenna electrical axis inconsistency beam waveguide polarized beam gain loss
