Underwater Warfare and Security

New technology and new threats call for new sonar systems. Our research includes the design of new sonar concepts, sonar signal processing (array processing, waveform design, false alarm reduction…) and assessment or improvement of existing systems. Very often, the results of our research is put to operational use, either in technology demonstrators (Flank Array Towed Array demonstrator) or the development of brand new systems (The MAPS operational Low Frequency Active Sonar). To support our research, we develop and use an array of models for target signatures and response, oceanographic phenomena, acoustic propagation and sonar performance.
