针对低轨通信卫星系统低损耗、低时延和高指向精度等特点,基于对混合波束赋形技术原理与优势的分析,研究一种适用于低轨通信卫星系统的混合波束赋形架构——“模拟波束赋形网络+数字波束赋形网络”,采用多通道射频前端芯片、混频芯片及数字波束赋形专用芯片(ASIC),与瓦片式相控阵天线阵列高度集成,在满足可扩展/拼接阵面的基础上,实现性能、成本、复杂性和功耗等因素的综合优化,为未来我国实现天基物联和可重构相控阵天线系统提供参考。
Due to the characteristics of low earth orbit (LEO) communication satellite system like low propagation loss
small propagation delay and high pointing accuracy
a hybrid architecture-“analog beamforming stage and digital beamforming (DBF) stage” was proposed
and the principle and advantages of hybrid beamforming were analyzed.Through three dimensional integrating of multi-channel RF frontend chips
mixers
dedicated DBF ASIC chips
and tiles phased array anntena arrays
the proposed hybrid beamforming could be expanded or spliced.This hybrid architecture achieved the optimization of performance
cost
complexity and power consumption
and provided a reference for China to build space based internet of things system and reconfi gurable phased array antenna system in the future.
