Ambiguity of rotating-element electric-field vector method and elimination method

  • 摘要: 对旋转矢量法用于相控阵天线校准时的多解问题及其消除方法进行了研究.采用旋转矢量法对相控阵天线进行校准时会得到两组解,其中一组是伪解.通过理论推导对旋转矢量法中解的二义性进行了分析,给出了两组解的物理意义;然后通过对求解量进行变换给出了一种基于多轮测试的旋转矢量法解的二义性消除方法;最后通过理论分析和数值仿真对该方法的有效性进行了验证.结果表明,通过设置多组不同的初始相位分布,进行多轮旋转矢量测试,可有效消除解的二义性,该方法具有可操作性强、对测试系统要求低等优点.
