Abstract

L’invention se rapporte à un système radar d’imagerie à entrées et sorties multiples de type MIMO, comprenant : - des voies d’émission (Ve1, VeM,) ; - des voies de réception (Vr1, VrN) ; - des éléments rayonnants (ERe1, EReM, ERr1, ERrN) colocalisés formant un réseau antennaire en deux dimensions, chaque élément rayonnant (ERe1, EReM, ERr1, ERrN) ayant un domaine de couverture instantané prédéfini ; chaque élément rayonnant étant formé par une pluralité de p sous-éléments rayonnants (SeElt1, SsEltp) répartis selon au moins une des deux dimensions du réseau antennaire, le radar comprenant une pluralité de modules de dépointage électronique (MDe1, …, MDrN), chaque module de dépointage électronique étant connecté à un élément rayonnant, chaque module de dépointage étant configuré pour appliquer une commande de dépointage (Cmd) entre tous les sous-éléments rayonnants (SeElt1, SsEltp) d’un même élément rayonnant, la commande de dépointage (Cmd) étant identique d’un élément rayonnant à l’autre, de façon à déplacer le domaine de couverture de chaque élément rayonnant dans une même direction.
