Researchers have developed NADAFD, a novel framework designed to defend against backdoor attacks in federated learning for Synthetic Aperture Radar (SAR) image target recognition. This framework integrates frequency-domain, spatial-domain, and client-behavior analyses to identify and mitigate hidden backdoor triggers. NADAFD employs a noise-aware adversarial training strategy and a dynamic health assessment module to enhance model robustness against both backdoor threats and SAR speckle noise, demonstrating improved accuracy and reduced attack success rates in experiments.
