Abstract
Réseau moins sensible aux lobes latéraux. Il comprend une rangée unique d'éléments transducteurs électro-acoustiques 11 constituant un réseau d'émission avec éléments d'émission unitaires T, TR également répartis et un réseau de réception avec éléments de réception unitaires TR, R également répartis, l'écartement entre éléments d'émission unitaires étant sensiblement différent de l'écartement entre éléments de réception unitaires, de sorte que le lobe latéral indésirable à l'émission fait, par rapport au faisceau principal un angle sensiblement différent de celui que fait, à la réception le lobe latéral indésirable par rapport au faisceau principal et que le produit des sensibilités reatives aux lobes latéraux est faible. Application au domaine médical.
