Title
(FR) SYSTEME DE DETECTION ET DE LOCALISATION D'UNE PERTURBATION D'UN MILIEU, PROCEDE ET PROGRAMME D'ORDINATEUR CORRESPONDANTS
Abstract
(FR)
Le système comporte des moyens d'émission (304, 306) d'ondes acoustiques successives dans le milieu (102), des moyens de réception (308) des ondes acoustiques successives après leur propagation dans le milieu (102), conçus pour fournir un signal de réception à partir des ondes acoustiques successives reçues, et des moyens de détection et de localisation de la perturbation dans le milieu à partir du signal de réception. Les moyens d'émission (304, 306) sont conçus pour que, le spectre d'amplitude et/ou de phase de chaque onde acoustique présentant, à au moins une certaine fréquence, une amplitude, respectivement une phase, variant dans le milieu suivant une certaine répartition spatiale d'amplitude, respectivement de phase, ces répartitions spatiales d'amplitude, respectivement de phase, des ondes acoustiques successives soient différentes entre elles.
