Recent advances of phased array application in satellite-terrestrial convergence networks
摘要
Abstract
Ubiquitous and low-latency broadband access services can be obtained with the convergence of satellite and terrestrial networks.Phased array has the advantages of low-profile,flexible beamforming and rapid configuration of parameters,and it has been treated as the ideal candidate radio frequency front-end in information transmission between satellites and terrestrial terminals.However,phased array must cope with the challenges of reducing cost and power consumption,increasing broadband transmission capacity and improving wide-angle scanning performance.Most existing reviews concentrate on the design and manufacturing process of phased arrays.Different from these works,focuses on the recent advances of phased array application in satellite-terrestrial convergence networks.Firstly,we elaborate on basic architectures and characteristics of phased array.Then,we summarize several key technologies to address the challenges,such as beam staring,high-precision beam pointing,low-cost design and multi-beam beamforming ability.Finally,we envision the future development trends and research directions in multiple scenario,such as distributed satellite clusters,high-frequency evolution and the integration of communication and sensing.关键词
