摘　　要：在复杂山地条件下,传统的无线侦察方式面临诸多干扰和困难。对此,提出了一种利用智能反射面在山地侦察中构建反射视距侦察链路以提高链路整体侦察效果的设计方案。具体而言,考虑公平性和整体效率,以最大化加权侦察信噪比和最大化最小侦察信噪比为目标,对反射波束赋形向量进行优化设计。仿真结果表明,所提方案能够显著提升链路侦察效果。In complex mountain conditions,conventional wireless reconnaissance methods face many interferences and difficulties.In this regard,this paper proposes a design scheme that utilizes IRS(Intelligent Reflecting Surface)to construct a reflective line-of-sight reconnaissance link in mountain reconnaissance to improve the overall reconnaissance effect of the link.Specifically,it takes fairness and overall efficiency into consideration,and optimizes the design of the reflective beamforming vectors with the goal of maximizing the weighted reconnaissance SNR(Signal-to-Noise Ratio)and maximizing the minimum reconnaissance SNR.Simulation results indicate that the proposed scheme can significantly improve the link reconnaissance effect.
