Space-time methods for inverse problems in acoustics with applications in sound source tracking
Context
Conventional localization methods, such as classical delay-and-sum beamforming and MVDR beamformers, encounter significant difficulties in challenging acoustic environments, as they struggle to separate sound sources effectively. Space-Time methods, which have already proven successful in RADAR in low signal-to-noise ratio or cluttered environments, are a promising alternative. In acoustics, these methods have received little attention in application to inverse acoustic problems, although they represent a suitable class of algorithms for localization tasks.
The objective of this Ph.D. project is to research and develop novel space-time acoustic tracking methods that enable accurate and reliable localization of sound sources, while operating in acoustically challenging environments. The space-time acoustic tracking algorithm will be implemented with the goal to effectively handle low signal to noise ratio conditions and the ability to separate multiple sound sources.
A comparative analysis of the proposed space-time acoustic tracking method with traditional methods will be carried out. The accuracy, reliability, and real-time capabilities of the developed method will be assessed within the work.
This research project will involve several phases, including a literature review, development of a space-time localization and tracking algorithm, data evaluation and presentation of research results. Ultimately, the work will culminate in a doctoral thesis in applied mathematics.
Participation in international congresses and writing of scientific papers in top-tier journals will be supported and strongly encouraged.
