Résumé

Les systèmes acoustiques marins qui sont rapidement déployés au fond de la mer, et qui fonctionnent avec autonomie, offrent une méthode de recherche qui est de faible cout, mais qui donne une pauvre connaissance de les positions des récepteurs. Pacreque la validité des manipulations des donnés, comme celles obtenues par le Matched Beam Processing, est fortement dépendente sur la location des instruments, une précise determination de la position de l’instrument est nécessaire. Ce papier décrit la méthode de Localization des Éléments d’Étalage (AEL) et son utilization dans la localization du système ULITE, un étalage horizontal déployé dans la mer de Timor pendant l’essai RDS-2 de l’an 1998. La question iverse mal posée, celle de la determination des positions de les sources (des ampoules implosées) et les récepteurs par les tems d’arivee relatifs des transients de source, est résolu par l’inversion linéale régularisée. La solution d’inversion est une excellente réprésentation de les donnés, et donne les positions de chaque hydrophone en accordance avec un model qui donne la forme optimale a l’étalage acoustique, et qui est consistent avec les donnés acoustiques.
