| 摘 要： | 针对矩形暗室内多径反射对天线测量精度的影响,引入了间接时域加门的方法;该方法利用逆傅里叶变换对宽带扫频数据进行处理获得天线的时域响应,然后采用时间门去除多径信号,变换到频域后可获得较准确的天线电参数,如方向图等;同时为了减少时域响应的泄漏,进一步提高测量精度,采用了基于频域加窗的逆傅里叶变换;对该方法进行仿真分析和实验验证,结果表明采用该方法得到的方向图与标准方向图基本吻合,具有一定的有效性和实用性。 |

| Abstract: | To eliminate the effects of multi-path reflections in anechoic chamber,time-gating method is introduced.The method employs Inverse Fourier Transform to deal with broadband sweep frequency data for obtaining the time domain response of antenna,then remove the reflection signals by means of time-gating to get more accurate electrical parameters of antenna.The measuring accuracy has been improved due to adopting Inverse Fourier Transform based on adding window in frequency domain.The simulation and experiment ... |
