UAV acoustic recognition in complex environments based on attention mechanism fusion and variational mode decomposition
An improved deep learning model, ResNet18_Attention, is proposed based on the traditional ResNet18, which effectively enhances the feature representation capability of UAVs under low SNRs, and the pro posed model achieves consistent improvements in accuracy, precision, recall, and F1-score under noisy conditions.
