Abstract

L'invention concerne un système radar destiné à surveiller au moins une zone de surveillance d'objets (18), un réseau d'antennes (22), un véhicule et un procédé pour faire fonctionner un système radar (12). Le système radar comprend une pluralité d'antennes d'émission (26) qui peuvent être activées par des signaux d'émission respectifs et au moyen desquelles des signaux de radar correspondants peuvent être envoyés dans au moins une zone de surveillance. En outre, le système radar comprend une pluralité d'antennes de réception (28) au moyen desquelles des échos de signaux radar émis peuvent être reçus et convertis en signaux de réception correspondants. Le système radar comprend également au moins un dispositif de commande et d'évaluation (24), qui est relié aux antennes d'émission (26) et aux antennes de réception (28), et au moyen duquel des signaux d'émission sont produits pour assurer l'activation des antennes d'émission et au moyen duquel, sur la base de signaux de réception, des informations d'objet (r, φ, Θ) concernant des objets (18) détectés avec les signaux radar peuvent être déterminées. Les centres de phase (32) respectifs d'au moins quatre antennes de réception (28) sont disposés sur un axe longitudinal imaginaire de récepteur (46). Les centres de phase (32) respectifs d'au moins deux antennes de réception (28) voisines sont disposés à une distance de base (40) les uns des autres. Les centres de phase (32) respectifs d'au moins deux antennes de réception (28) voisines sont disposés à une distance longitudinale respective de récepteur (48a, 48b, 48c) les uns des autres, laquelle est supérieure à la distance de base (40).
