The invention relates to a device for detecting an obstacle at the rear of a vehicle, comprising at least one sensor (30, 31, 32), characterized in that it includes means for apodizing the distribution of the intensity emitted by the or each sensor (30), so as to modify the radiation pattern from the or each sensor. L'invention concerne un dispositif de détection d'un obstacle à l'arrière d'un véhicule comprenant au moins un capteur (30, 31, 32), caractérisé en ce qu'il comprend des moyens pour apodiser la distribution de l'intensité émise par le ou chaque capteur (30), afin de modifier le diagramme de rayonnement du ou de chaque capteur.
