1. A method for operating a communications system comprising an antenna array having a plurality of antenna elements, the method comprising:

  • receiving a plurality of signals at the 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;

    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 plurality of signals;

    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.
