Claim 25:
26. The method of claim 21 wherein:
the two or more pairs of Rx antenna elements comprises Rxn and Rxm,wherein n≠m;
the first selected pair of Tx antenna elements comprises Txi and Txk;
computing at least one relative gain value and at least one relative phase value for the Rx antenna element Rxn relative to the Rx antenna Rxm based on one or more of:
the gain measurement, GMTxiRxn, and the phase measurement, ϕMTxiRxn, for a pair of Tx and Rx antenna elements Txi and Rxn;
the gain measurement, GMTxiRxm, and the phase measurement, ϕMTxiRxj, for a pair of Tx and Rx antenna elements Txi and Rxm;
the gain measurement, GMTxkRxn, and the phase measurement, ϕMTxkRxn, for a pair of Tx and Rx antenna elements Txk and Rxn; and
the gain measurement, GMTxkRxml and the phase measurement, ϕMTxkRxm for a pair of Tx and Rx antenna elements Txk and Rxm;

repeating the steps of determining and computing for at least one second pair of Tx antenna elements, Txi and Txk, having symmetrical coupling properties with respect to the pair of Rx antenna elements, Rxn and Rxm.
