铁氧体移相器的近似计算

APPROXIMATE CALCULATION OF A FERRITE PHASE SHIFTER

资料[1]报导了一种在雷达上颇有用途的铁氧体移相器与天线阵:并介绍了该器件的部分优点,但并未对这种器件的理论分析作任何说明。目前,在国内、外的文献上均未见到对此类器件的理论分析作完整的叙述。本文提出了一种比较完善的关于铁氧体移相器的理论分析方法,进行了模型简化和近似处理:并用计算机进行了证验,结果较为符合实际情况,所以,我们认为,用这种方法对铁氧体移相器进行理论分析。

A ferrite phase shifterthat is quite useful in radar was reported in reference [1], and some advantages of it were described, but there was no theoritical analysis about it in that paper, also in another literatures. In this paper, better theoritical analysis method of ferrite phase shifter was presented, the model was simplified and calculation was carried out; the results agree with experiments. So it was considered that the calculation method of ferrite phase shifter is useful for us to design a phase shifter。
