本文介绍了一种代替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,避免使用结构复杂的章动旋转关节,在经济上稳定性有显著的优越性。本文介绍了这种天线和馈源的设计思想,及据此研制出的天线。馈源和天线的实测值表明波束偏轴角的均匀性和极化性良好,在对线极化讯标跟踪时,天线姿态平稳,捕获目标快而准,其跟踪效果是令人满意的。
This paper introduces a conical scanning self-tracking receiving antenna instead of a nutation feed, which is used to avoid the use of complicated structure of nutating joints when tracking linearly polarized beacons. It has significant economic stability. This paper introduces the design idea of this kind of antenna and feed, and the antenna developed accordingly. The measured values of the feed and the antenna indicate that the uniformity and polarization of the off-axis beam are good. When tracking the line polarization, the attitude of the antenna is stable and the target is fast and accurate. The tracking effect is satisfactory.
