摘要
根据时域带通原理编写了吸波材料与天线性能测试及分析的Matlab程序,利用该程序能够实现对多组数据的比较分析,为确定合理的时域门参数提供依据;天线方向图处理程序也能够绘出不同时域门宽度、不同β值的天线方向图和半功率波瓣宽度图,降低了对天线测试场地的要求,为准确测量天线性能提供了一种高效的方式。
According to the principle of the time domain band-pass mode, two programs are developed for RF absorbing material and antenna performance measurement and analysis.The RF absorbing materialtest program could compare test data with different time gating parameters, which provides basis for the setting of reasonable time gating parameters.The antenna pattern processing program could plot various antenna radiation pattern and the half-power beam width pattern based on different time gating widths and values of beta. It reduces the requirement for antenna test site and provides an effective method for accurate measurement of antennas＇ performance.
