Fast sparse adversarial attack for synthetic aperture radar target recognition

HIGHLIGHTS

• What: To solve the problem of long computation time in existing SAR sparse adversarial attack algorithms the authors propose a SAR fast sparse adversarial attack (FSAA) algorithm. The aim of D2 is to generate a sparse perturbation image. In this study, the L2 norm was introduced to measure the degree of distortion of the original SAR image x and the adversarial example x~ to ensure that the adversarial example generated by the algorithm in this study cannot be detected by the human eye. To verify the attack effectiveness and concealment of the FSAA algorithm proposed in this . . .
