Cost-Sensitive Awareness-Based SAR Automatic Target Recognition for Imbalanced Data

With the maturity of synthetic aperture radar (SAR) technology, the problem of imbalanced data has gradually emerged. This problem makes it difficult for the automatic target recognition (ATR) model to properly learn the classification boundaries of majority and minority category target samples. In...
