色散馈电天线系统输入阻抗的扫频测量

The swept frequency measurement of input impedancein the dispersive feed antenna system

对用网络分析仪（ＨＰ８５１０Ｃ）扫频测量色散馈电天线系统输入阻抗的方法进行了研究；指出了网络分析仪时域测量的局限性；并从误差模型理论的基本原理出发，提出了工程中实用的校准、测量方法．依据该方法进行了实际测量。

The method for the network analyzer (HP8510C) to sweep input impedance in the dispersive feed antenna system is discussed. The limitation of time domain measurement by the network analyzer is pointed out. A practical calibration and measurement method used in engineering is proposed on the principle of an error model. The results of the practical measurement are in good agreement with theorical value.
