摘要
介绍了相控阵天线的远场校准方法——旋转矢量法,利用HFSS仿真软件对4×4元相控阵天线扫描角为0°状态进行校准仿真,效果优良;在宽角校准时,采用旋转矢量法结合最大值法进行校准,用CST仿真软件结合该方法进行仿真,效果良好;最后进行试验测试,对4×4元相控阵天线在两维宽角范围内进行校准。结果证明该方法能有效校准小阵面宽角扫描相控阵天线。
The Rotating-element Electric field Vector（REV） method,for far field calibration of Phased Array Antenna（PAA）,was proposed in this study.First,a 4×4 two-dimensional PAA was commendably calibrated at 0° scanning angle for using REV method by HFSS.Then,a method combining maximum method was used in wide scanning angle calibration with CST,which showed good effect.At last,a test was carried out.The results indicate that the method is valid for small PPA in wide scanning angle.
