Abstract

La présente invention porte sur un dispositif de sonar attaché à une coque et sur un navire ayant le dispositif de sonar, lesquels comprennent : une unité d'hydrophone comportant un ou plusieurs hydrophones pour détecter un signal sonore sous l'eau et délivrer en sortie à l'intérieur de celle-ci un signal électrique ; une unité de réception dans laquelle est disposée l'unité d'hydrophone ; et une unité de sonar pour recevoir l'unité d'hydrophone et l'unité de réception, et comportant un boîtier formé de façon à permettre au signal sonore de traverser celui-ci, l'unité de sonar étant attachée à la surface latérale du navire sous une forme saillante ou sous une forme d'immersion. Par conséquent, des performances de détection pour un son à moyenne et à basse fréquences sont améliorées grâce au changement d'une longueur de groupement du dispositif de sonar par connexion mutuelle du nombre requis de modules de sonar unitaires en fonction de la longueur du navire, et analogue, et une onde sonore est facilement détectée même pendant une mobilité élevée ou un repos.
