PROBLEM TO BE SOLVED: To provide a method of repointing a reflector array antenna. SOLUTION: The method repoints a reflector array antenna and samples signals received by the antenna which comprises a plurality of radiation elements and is of the type that forms beams by computation. The method comprises operations of estimating the deviation in the pointing of a radiation pattern of the antenna to obtain a phase shift matrix, calculating the inverse discrete Fourier transform of signal samples fed by the radiating elements, multiplying the phase shift matrix by the inverse Fourier transform of the sampled signals, and computing the discrete direct Fourier transform of the product of the phase shift matrix and the inverse Fourier transform of the sampled signals.
