标题： Secure Pinching Antenna-aided ISAC

摘要： 在本信中，研究了一种借助夹钳天线（PA）的方案，以建立一个安全的集成感知与通信系统（ISAC）。 该基础系统包括一个双功能雷达通信（DFRC）基站（BS），通过多个波导连接，为多个下行用户服务，同时在给定区域感知一组恶意目标。 借助PA的BS旨在保持与合法用户的通信机密性，同时能够检测恶意目标。 所提出方案的一个目标是优化PA的位置，基于此提供合法信号波束成形和人工噪声协方差矩阵的最佳设计，以在保密性和总功率约束下最大化网络的感知性能。 我们通过数值示例展示了所提方案的有效性，并将其与具有半波长间距天线的常规DFRC ISAC系统进行了比较。 我们表明，在照明功率方面，所提出的方案比具有等距PA的基准PA辅助方案高出$3$dB，同时与具有半波长间距均匀线性阵列的传统ISAC系统相比，同一指标的增益可达$30$dB。 显示英文摘要

摘要： In this letter, a pinching antenna (PA)-aided scheme for establishing a secure integrated sensing and communication system (ISAC) is investigated. The underlying system comprises a dual-functional radar communication (DFRC) base station (BS) linked to multiple waveguides to serve several downlink users while sensing a set of malicious targets in a given area. The PA-aided BS aims at preserving communication confidentiality with the legitimate users while being able to detect malicious targets. One objective of the proposed scheme is to optimize the PA locations, based on which an optimal design of the legitimate signal beamforming and artificial noise covariance matrices is provided to maximize the network's sensing performance, subject to secrecy and total power constraints. We demonstrate the efficacy of the proposed scheme through numerical examples and compare that against a traditional DFRC ISAC system with a uniform linear array of half-wavelength-spaced antennas. We show that the proposed scheme outperforms the baseline PA-aided scheme with equidistant PAs by $3$ dB in terms of illumination power, while it can provide gains of up to $30$ dB of the same metric against a traditional ISAC system with half-wavelength-space uniform linear arrays.
