【摘要】 本文介绍了一种不用章动馈源的圆锥扫描自跟踪接收天线,用于对线极化信标跟踪时,避免了使用结构复杂的章动旋转关节,不但成本低而且稳定性也较好。馈源和天线的实测值表明:波束偏轴角的均匀性和极化性能良好,在对线极化信标跟踪时,天线姿态平稳、捕获目标快而准,获得了令人满意的跟踪效果。更多还原

【Abstract】 In this paper, a scheme of an auto-tracking antenna is given to replace the complex nutating conical-scan antenna. The measured values of the feed and antenna show that the angles of the beam deviated from the antenna axis in any plane are almost the same and the polarization performance is excellent. In tracking the signal target with linear polarization, the target is catched out quickly and exactly, and the situation of the antenna is stable.更多还原
