지능적 레이더가 단일 차원 복잡한 베이스 밴드 시퀀스의 끝에서 끝까지 처리하는 방향으로 진화함에 따라 깊은 네트워크는 심각한 적대적 위협에 직면합니다.그러나 기존의 공격은 실용적인 전자 전투에서 두 가지 제한에 직면합니다: 낮은 크로스 아키텍처 전송 가능성과 물리적 채널 왜곡에 대한 심각한 취약성, 이는 전술적 신뢰성을 약화시킵니다.이 곤경을 극복하기 위해, 우리는 물리적 미리 구분된 공간-시간 공격 (SSTA)을 제안합니다.

Abstract

As cognitive radars evolve towards the end-to-end processing of one-dimensional complex baseband sequences, deep networks face severe adversarial threats. However, existing attacks encounter dual limitations in practical electronic warfare: low cross-architecture transferability and severe vulnerability to physical channel distortions, which degrades their tactical reliability. To overcome these bottlenecks, we propose a physical prior-driven Segmented Spatio-Temporal Attack (SSTA). First, a global-local feature decoupling segmentation mechanism interrupts the adversarial gradients' dependence
