The paper presents an overview of the inverse problems associated with applications of underwater acoustics. The problems are classified into four main categories, according to the recoverable quantities : Acoustic source localization, bottom identification, ocean acoustic tomography and target recognition. The paper gives emphasis to the three first categories, and includes methods to solve th...

This paper describes the capability, design and application of the generic underwater warfare simulation environment ODIN. The model was developed by QinetiQ, previously DERA (Defence Evaluation and Research Agency), to model the detailed underwater interaction between surface ship/submarine/UUV (Unmanned Underwater Vehicle) platforms, torpedoes and countermeasures. It was originally developed ...

Almost three years have passed since the publication of first Special Issue on three-dimensional underwater acoustics in 2019 [...]
