Towards Assessing the Synthetic-to-Measured Adversarial Vulnerability of SAR ATR

1 code implementation30 Jan 2024 Bowen Peng, Bo Peng, Jingyuan Xia, Tianpeng Liu, Yongxiang Liu, Li Liu

Recently, there has been increasing concern about the vulnerability of deep neural network (DNN)-based synthetic aperture radar (SAR) automatic target recognition (ATR) to adversarial attacks, where a DNN could be easily deceived by clean input with imperceptible but aggressive perturbations.

Learning Invariant Representation via Contrastive Feature Alignment for Clutter Robust SAR Target Recognition

no code implementations4 Apr 2023 Bowen Peng, Jianyue Xie, Bo Peng, Li Liu

The proposed method contributes a mixed clutter variants generation strategy and a new inference branch equipped with channel-weighted mean square error (CWMSE) loss for invariant representation learning.

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).
