<p>A phased array antenna is calibrated by obtaining time-dependent signals from respective ones of the antenna outputs and computing Hilbert transforms of the time dependent signals. Products of complex signals formed from the time dependent signals and their Hilbert transforms are computed. Phase correction factors for the antenna outputs are estimated from the products. The estimated phase correction factors are used to set phase corrections applied to signals from the antenna outputs.</p>
