Acoustic Imaging for UAV Detection: Dense Beamformed Energy Maps and U-Net SELD

Researchers have developed a U-Net model for acoustic source localization using beamformed audio maps, enabling precise detection of sound sources like drones in 360-degree environments. This method segments active sound regions from beamformed energy maps, improving angular precision and adaptability across various microphone configurations, offering a new approach to dense spatial audio understanding beyond traditional methods.
