论文摘要
通过使用通用信号方法进行双功能雷达通信（DFRC）系统，窃听针对合法用户的消息的易感性恶化了。对于DFRC系统，雷达目标可以充当窃听器（ED），从而接收高能信号，从而导致其他挑战。与先前的作品不同，我们考虑了具有多个EDS的多播多端DFRC系统。然后，我们提出了一种物理层设计方法，以通过在雷达通道中安装智能反射表面来最大化保密率。我们优化了多个ED多播多端多Aantenna DFRC保密率（OPTM3SEC）方法，可以解决此高度非凸问题相对于预编码矩阵。我们的数值实验证明了我们算法在最大化此DFRC设置中的保密率的可行性。
With the use of common signaling methods for dual-function radar-communications (DFRC) systems, the susceptibility of eavesdropping on messages aimed at legitimate users has worsened. For DFRC systems, the radar target may act as an eavesdropper (ED) that receives a high-energy signal thereby leading to additional challenges. Unlike prior works, we consider a multicast multi-antenna DFRC system with multiple EDs. We then propose a physical layer design approach to maximize the secrecy rate by installing intelligent reflecting surfaces in the radar channels. Our optimization of multiple ED multicast multi-antenna DFRC secrecy rate (OptM3Sec) approach solves this highly nonconvex problem with respect to the precoding matrices. Our numerical experiments demonstrate the feasibility of our algorithm in maximizing the secrecy rate in this DFRC setup.
