Dual-stage learning framework for underwater acoustic target recognition with cross-attention mechanism and audio-guided contrastive learning

Underwater acoustic target recognition is crucial for marine exploration and environmental monitoring. However, the redundancy in raw time-domain signals and the challenges in effectively integrating time-frequency representations with audio features hinder current methods. To address these challeng...
