title = "Joint Optimization Design for Active RIS-Assisted Maritime Secure ISAC System",
abstract = "This research investigates the application of Integrated Sensing and Communication (ISAC) systems in maritime secure communication networks. Considering the severe path loss caused by complex maritime environments, we employ an active Reconfigurable Intelligent Surface (RIS) to establish supplementary communication links and enhance system performance. The primary objective is to maximize the sum secrecy rate (SSR) through the joint optimization of the hybrid precoding at the Dual-Function Base Station (DFBS) and the phase shift matrix of the active RIS, subject to both transmit power constraints and sensing performance requirements. We propose an alternating optimization algorithm based on fractional programming (FP) and successive convex approximation (SCA) techniques to solve this joint optimization problem. Numerical results demonstrate that the proposed algorithm achieves up to 10\% SSR gain compared to passive RIS schemes, while maintaining excellent convergence performance.",
