Abstract

This paper delves into the realm of dual-polarized reconfigurable intelligent surface (DP-RIS)-assisted secure integrated sensing and communication (ISAC) systems, leveraging the radar sensing signal as the interference to disturb the potential eavesdropper. A joint optimization problem for the transmit beamforming and sensing covariance matrices of the base station (BS), and phase shift matrix of the RIS is formulated in order to maximize the achievable secrecy sum rate (ASSR). The non-convex problem is decomposed into two sub-problems, which are solved iteratively utilizing successive convex approximation and semi-definite programming methods. Simulation results show that the proposed DP scheme achieves significantly superior ASSR compared to the single-polarized (SP) scheme, all while satisfying the performance requirement for multi-target detection.

双极化 RIS 辅助安全综合传感与通信系统

本文研究了双极化可重构智能表面（DP-RIS）辅助安全集成传感与通信（ISAC）系统领域，利用雷达传感信号作为干扰干扰潜在窃听者。为了使可实现的保密和速率（ASSR）最大化，提出了基站发射波束形成和感知协方差矩阵（BS）与RIS相移矩阵的联合优化问题。将非凸问题分解为两个子问题，利用连续凸逼近和半确定规划方法进行迭代求解。仿真结果表明，该方案在满足多目标检测性能要求的同时，显著优于单极化（SP）方案。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
