Scattering Model Guided Adversarial Examples for SAR Target Recognition: Attack and Defense

1 code implementation11 Sep 2022 Bowen Peng, Bo Peng, Jie zhou, Jianyue Xie, Li Liu

Toward building more robust DNN-based SAR ATR models, this article explores the domain knowledge of SAR imaging process and proposes a novel Scattering Model Guided Adversarial Attack (SMGAA) algorithm which can generate adversarial perturbations in the form of electromagnetic scattering response (called adversarial scatterers).
