Abstract
The method consists in the step of masking the energy influence of the aliased spectrum of a jammer received in the useful band of each of the reception channels of a radio station during a determined time interval surrounding the change-over instant of each antenna. The masking is done either by means of attenuators with diodes placed at the input of each of the reception channels and controlled during the determined time interval or by memorizing, at least during the time interval, the gain of the intermediate frequency amplifiers before the change over takes place, by opening the automatic gain control loop of the intermediate frequency amplifiers to stabilize the gain of each amplifier, during the change over, at its memorized gain value.
