Physics-constrained diffusion-based data augmentation for active sonar under low-SNR sea conditions
The limited availability of real sea-trial target echoes restricts the training of data-driven active sonar detection models. Simulated echoes can increase the sample size, but their distributions often differ from those of real ocean environments. To address this problem, this paper proposes a physics-constrained two-...
