摘要
通信和感知一体化是6G的关键技术之一,但目前的研究主要聚焦于地面移动通信系统,针对卫星通感一体化的研究却鲜有涉及。介绍了通感一体化和面向6G的发展趋势,以及卫星技术的现状和6G天地一体化发展方向,对面向6G的卫星通感一体化及其关键技术,包括星地协作的通感一体化方案、新型通感一体化波形设计、波束赋形和干扰消除等关键技术进行了探讨和展望,为进一步开展6G卫星通感一体化研究奠定基础。
Integrated sensing and communication is one of the key technologies for 6G,current research mainly focuses on the terrestrial mobile communication system,but rarely on satellite.Therefore,the development trend of integrated sensing and communication for 6G as well as the state of art of satellite technology and the trend of 6G space-ground integration are first introduced.Furthermore,satellite integrated sensing and communication and its key technologies are investigated and prospected,including the integrated sensing and communication scheme based on satellite-ground collaboration,novel waveform design for integrated sensing and communication,beamforming,interference elimination,etc.This work lays a solid foundation for further research on satellite integrated sensing and communication for 6G.
