随着双功能雷达通信（DFRC）系统中常用信令方法的使用，针对合法用户的消息窃听的敏感性已经恶化。对于DFRC系统，雷达目标可以充当接收高能量信号的窃听者（艾德），从而导致额外的挑战。与以前的作品不同，我们考虑了多个ED的多播多天线DFRC系统。然后，我们提出了一个物理层的设计方法，通过安装智能反射表面的雷达通道，以最大限度地提高保密率。我们的优化多个艾德多播多天线DFRC保密率（OptM3Sec）的方法解决了这个高度非凸的预编码矩阵的问题。我们的数值实验表明，我们的算法在最大化的保密率在DFRC设置的可行性。
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.
