Sonar Systems for Objects Recognition

Yan Pailhas

Research output: ThesisDoctoral Thesis


The deep sea exploration and exploitation is one of the biggest chal- lenges of the next century. Military, oil & gas, offshore wind farming, underwater mining, oceanography are some of the actors interested in this field. The engineering and technical challenges to perform any tasks underwater are great but the most crucial element in any underwater systems has to be the sensors. In air numerous sensor systems have been developed: optic cameras, laser scanner or radar systems. Unfortunately electro magnetic waves propagate poorly in water, therefore acoustic sensors are a much preferred tool then op- tical ones. This thesis is dedicated to the study of the present and the future of acoustic sensors for detection, identification or survey. We will explore several sonar configurations and designs and their corresponding models for target scattering. We will show that ob- ject echoes can contain essential information concerning its structure and/or composition.
