Title (EN) METHOD AND DEVICE FOR TRACING AN OBJECT
(FR) PROCEDE ET DISPOSITIF DE DETECTION D'UN OBJET
Abstract: front page image
(EN)In a method and a device for tracing an object (2a), especially a subsea object, whilst utilizing a mother vessel (1) or an intermediate craft (101) equipped with sonars (3a) for the transmission and reflection of searching rays (3b, 3n) which on a display on the vessel (1) indicate one or more objects (2a) in the subsea search area, it is suggested that there is used a searching unit (2) which is controlled from the vessel (1), and which comprises at least one transponder/responder (10, 13) or similar, for the transmission of signals corresponding to the searching rays (3b), and that said signal(s) is registered on the display on the mother vessel (1) and is used for guiding the searching unit (2) towards a selected object (2a) along the searching rays (3b, 3n) of the sonars.
(FR)Procédé et dispositif de détection d'un objet (2a), notamment sous-marin, à l'aide d'un vaisseau-mère (1) ou d'une embarcation intermédiaire (101), muni de sonars (3a) émettant et réfléchissant des rayons de sondage (3b, 3n). Un écran sur le vaisseau (1) indique la présence d'un ou plusieurs objets (2a) dans la zone sous-marine sondée. On se sert d'une unité de sondage (2) commandée à partir du vaisseau-mère (1) et comportant au moins un répondeur (10, 13) ou analogue destiné à la transmission de signaux qui correspondent aux rayons de sondage (3b). Ces signaux s'affichent sur l'écran du vaisseau-mère (1) et permettent le guidage de l'unité de sondage (2) vers un objet sélectionné (2a) le long des rayons de sondage (3b, 3n) émis par les sonars.
