摘要: 本文介紹了一種不用章動饋源的圓錐掃描自跟蹤接收天線,用于對線極化信標跟蹤時,避免了使用結構復雜的章動旋轉關節(jié),不但成本低而且穩(wěn)定性也較好。饋源和天線的實測值表明:波束偏軸角的均勻性和極化性能良好,在對線極化信標跟蹤時,天線姿態(tài)平穩(wěn)、捕獲目標快而準,獲得了令人滿意的跟蹤效果。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.
