Abstract
A method for suppressing a parasite signal received with a useful signal by a network of elementary antennas of a payload of a satellite. The suppression method includes an analogue formation step for forming analog beams and a digital formation step for forming a digital beam. The analog formation step includes forming of an useful analog beam in which the parasite signal is attenuated with respect to the useful signal and of an auxiliary analog beam in which the useful signal is attenuated with respect to the parasite signal. The digital formation step includes forming of a digital beam in which the parasite signal has been suppressed, by combining the signals obtained by digitizing the auxiliary beam and the useful beam.
