摘要
文章介绍了对相控阵各个单元信号的初始相位及幅度进行幅相校正的简单方法——旋转矢量法。在测量中仅涉及幅度测量而没有相位的测量,大大减化了测量的复杂性与难度。文章进行了计算机的仿真计算,结果证明采用该方法可以有效地改进天线的辐射性能。
A simplified method of phased array antenna calibration- rotation vector method is introduced. Only the amplitude is involved in measurement without phase so that the complexity and difficulty of measurement are greatly reduced. The simulation is carried out and the result shows the property of radiation of antenna is improved by using this method.
