Abstract :
This paper addresses the design of a signal pre-processor dedicated to passive acoustic tomography. Blind processor of channel´s spatial response is proposed and adapted with wide band transient signals such as when marine mammals vocalize. Full validation of this processor is performed on realistic synthetic data.
