报告摘要:

The complex problem of localizing sound sources with different motion patterns is addressed in this study, especially on the identification and separation of rotating and static sound sources. An innovative method is proposed that integrates Modal Combined Beamforming (MCB) with the equivalent source approach, leveraging the unique spatio-temporal properties of rotating and static sound sources. And a complete propagation matrix is constructed, then the Rotating-Static Sources Power Propagation (R-S2P) model is introduced to the intricate interactions between the sound sources and their environment. This R-S2P model is effectively solved by using the Least Absolute Shrinkage and Selection Operator (LASSO) within an Alternating Direction Method of Multipliers (ADMM) algorithm. The effectiveness of this method is rigorously tested through extensive simulations and real-world experiments.
