基于IRS辅助的舰载DFRC系统感知性能优化方法
IRS-assisted Sensing Performance Optimization Method for Shipboard Dual-function Radar and Communication(DFRC)Systems
摘要
Abstract
The integration of radar and communication is an effective solution to the problem of marine spectrum scarcity in recent years,which can be used for efficient communication and sensing.In order to reduce the path loss on the complex sea surface,the intelligent reflecting surface(IRS)is introduced into the dual-function radar communication(DFRC)system to improve the signal quality by adding additional paths.At the same time,the performance optimization problem of radar communication integration is constructed to maximize the radar signal-to-interference-plus-noise ratio(SINR)under the condition of satisfying the constraints of communication SINR,transmission power and IRS reflection power.An alternating optimization algorithm based on the majorization-minimization(MM)framework is proposed.Firstly,the original high-dimensional optimization problem is decomposed into two low-complexity sub-problems.Then,the non-convex sub-problem is transformed into a quadratic constrained quadratic programming problem which is easy to be solved by MM algorithm.Finally,the semi-definite relaxation algorithm is used to iterate until convergence.The simulation results show that the SINR of the radar is improved by more than 3 dB under the same reflection coefficient.关键词
