    • A method for operating a communications system is provided. The method includes receiving a plurality of signals at a plurality of antenna elements, the plurality of signals arriving at the array of antenna elements at a plurality of angles of arrival (AOAs) with respect to a reference location. The method also includes calculating a plurality of differential distance vectors between the plurality of antenna elements and the reference location, each of the plurality of differential distance vectors associated with one of the plurality of AOAs and at least one of the pluralities of signals. The method further includes obtaining a plurality of actual phase center locations for the plurality of antenna elements based on the plurality of differential distance vectors and the plurality of AOAs and providing a correction to configuration data for the array of antenna elements based at least on the plurality of actual phase center locations.
    • 提供了一种用于操作通信系统的方法。 该方法包括在多个天线元件处接收多个信号,该多个信号以相对于参考位置的多个到达角(AOA)到达天线元件阵列。 所述方法还包括计算多个天线元件与参考位置之间的多个差分距离矢量,所述多个差分距离矢量中的每一个与所述多个AOA中的一个和所述多个信号中的至少一个相关联。 该方法还包括基于多个差分距离向量和多个AOA获得多个天线元件的多个实际相位中心位置,并且至少基于多个天线元件为天线元件阵列提供对配置数据的校正 的实际相位中心位置。
