Journal ArticleIntegrated Sensing and Communication Under DISCO Physical-Layer Jamming AttacksHuang, Huan; Zhang, Hongliang; Mei, Weidong; Li, Jun; Cai, Yi; Swindlehurst, A Lee; Han, ZhuIntegrated sensing and communication (ISAC) systems traditionally presuppose that sensing and communication (S&C) channels remain approximately constant during their coherence time. However, a “DISCO” reconfigurable intelligent surface (DRIS), i.e., an illegitimate RIS with random, time-varying reflection properties that acts like a “disco ball,” introduces a paradigm shift that enables active channel aging more rapidly during the channel coherence time. In this letter, we investigate the impact of DISCO jamming attacks launched by a DRIS-based fully-passive jammer (FPJ) on an ISAC system. Specifically, an ISAC problem formulation and a corresponding waveform optimization are presented in which the ISAC waveform design considers the trade-off between the S&C performance and is formulated as a Pareto optimization problem. Moreover, a theoretical analysis is conducted to quantify the impact of DISCO jamming attacks. Numerical results are presented to evaluate the S&C performance under DISCO jamming attacks and to validate the derived theoretical analysis.IEEE2024-11-0110598712IEEE Wireless Communications Letters13113044 to 30482162-2337https://doi.org/10.1109/LWC.2024.34393982107182; 2030029National Science Foundation
