For our implementation and preprocessing, we treat the 256-dimensional intermediate-frequency echo signals with two crucial steps. We apply Global Normalization to eliminate scale differences and ensure stable gradients, and we use Label Smoothing to convert hard binary labels into soft labels (e.g., 0.9), which prevents the model from becoming overconfident and significantly mitigates the risk of overfitting.
