Real-time geoacoustic inversion of large band signals

This paper describes the development of a real time geoacoustic inversion tool devoted to large band signals. The aim of this tool is to automatically infer geoacoustic bottom characteristics from transmission sound field pressure measurements in a deep ocean medium. The first part of the article is devoted to the direct problem. It describes the functionalities of the propagation simulation tool and its automatic connection with measurements parameters. Then the paper deals with an inversion method based on recent works on the subject in the scientific community. Finally real-time architecture and some concrete results obtained with in situ data in the Gulf of Oman are presented.
