无人机场景下基于宽带可重构超表面的聚束成像感知协同通信设计
Design of Sensing-Coordinated Communication and Spotlight Imaging Based on Broadband Reconfigurable Metasurfaces in UAV
摘要
Abstract
Combining integrated sensing and communication(ISAC)with reconfigurable metasurfaces is crucial for low-cost,energy-efficient airborne sensing and communication applications.However,the existing microwave airborne systems face the dual constraints of poor azimuth resolution caused by the short synthetic aperture time of conventional stripmap beams,and the difficulty in simultaneously maintaining a low bit error rate(BER).To address this issue,this paper first analyzes the principles of synthetic aperture radar(SAR)imaging and directional communication,identifying wideband hardware and dynamic beam control as core bottlenecks for efficient ISAC.Then a sensing-coordinated metasurface system is proposed to integrate high-resolution imaging and mobile communication.By utilizing a wideband 1-bit phase-quantized 2×8 metasurface array and OFDM waveforms for spotlight beam tracking,the system extends the observation time of targets and boosts the communication gain during flight.Simulations show the system overcomes the bandwidth limits,ensures high range resolution,substantially reduces the communication BER in mobile scenarios,and improves azimuth imaging resolution by approximately 28.5％,offering strong technical support for for the practical deployment of low-cost and wideband microwave ISAC technology.关键词
