| 摘 要： | 为了获得天线方向图、增益等参数的实测数据,研究了天线电参数的时域和频域测量方法,分别应用2种方法建设了天线方向性测量系统。以窄脉冲信号发生器和数字取样示波器为基础建设时域系统,分别以矢量网络分析仪和信号源加频谱仪为主体构建频域测量系统。给出了系统构成及组件的相互关系,确定了测量流程,提出了数据处理方法及关键技术。最后,对时域和频域两种测量方法的特点进行了比较。建设的测量系统为天线研制、验收等工作提供了技术手段。

| Abstract: | To achieve testing data of antenna parameters such as azimuth pattern and gain, a measurement system for antenna directivity is build using both time-domain and frequency-domain techniques. Time-domain measurement is built based on narrow pulse generator and digital sampling oscilloscope. Frequency-domain measurement system is built based on vector network analyzer or signal generator and spectrum analyzer. System constitution and ralatioons between elements together with measurement flow as well as key technology of each method are proposed. At last, the two methods for measurement of antenna are compared. The measurement systems are pratical technical means for engineering development and acceptance of antennas. |
