Abstract
The present invention relates to a method of repainting a reflector array antenna comprising a plurality of radiating elements and being of the type that forms beams by computation, in which method each signal received by said antenna is sampled.The method comprises the following operations:estimating the depointing of the radiation pattern of the antenna to obtain a phase shift matrix,computing the discrete inverse Fourier transform of the signal samples supplied by the radiating elements,multiplying the phase shift matrix by the inverse Fourier transform of the sampled signal, andcomputing the discrete direct Fourier transform of the product of the phase shift matrix and the inverse Fourier transform of the sampled signal.
