Résumé

En cet article nous considérons les problèmes communs de séparer et de localiser des trains de clic de cachalot. La separation de train de clic est le problème de simple-hydrophone de grouper les clics de chaque animal ensemble quand les clics de plus d’un animal sont présents à une hydrophone donnée. La localisation est le problème de localiser les animaux basés sur la mesure du temps retarde des mêmes événements de clic aux sondes multiples. Le problème deux sont en soi relies. Nous considérons d’abord les deux problèmes employant indépendamment des applications de nouveaux des méthodes statistiques de traitement des signaux. Pour la séparation, nous utilisons un algorithme inspireé par l’algorithme de Viterbi de la programmation dynamique. Pour la localisation, nous utilisons un algorithme inspireé par l’algorithme de E-M. En conclusion, nous employons les deux algorithmes pour nous aider dans une solution du joint localization/séparation. Nous démontrons l’algorithme sur de vraies données.
