Claim 9:
10. The method of claim 1 wherein performing the gain measurements, GMTxiRxj, and the phase measurements, ϕMTxiRxj, for the pairs of Tx and Rx antenna elements in the antenna array comprises, for each pair of Tx and Rx antenna elements Txi, Rxj:
transmitting a pseudo random IQ signal of a desired bandwidth while the transmit antenna element Txi and the Rx antenna element Rxj are active;
cross-correlating the transmitted pseudo random IQ signal and a received IQ signal received via the Rx antenna element Rxj; and
computing the gain measurement, GMTxiRxj and the phase measurement, ϕMTxiRxj, for the pair of Tx and Rx antenna elements Txi, Rxj based on results of the cross-correlating.
