摘 要:高通量卫星已经成为国内外民商卫星通信领域的主流,多波束排布技术作为高通量卫星系统设计的一项关键技术,与用户需求密切相关,对于提升系统的匹配容量和降低卫星的设计、制造成本至关重要。文章根据波束排布的特点将该技术划分为规则排布和不规则排布,系统性地总结了国内外、特别是国外高通量卫星多波束排布技术的最新研究进展,包括按区域分组的规则波束排布方法,以及不同大小圆形波束排布和不同参数椭圆波束排布的不规则波束排布方法。结合全灵活卫星系统灵活覆盖、高性价比设计及高轨高通量卫星发展的需求,提出后续高通量卫星多波束排布技术的发展趋势,例如,基于细颗粒度的用户级需求,以不同大小圆形波束排布和不同参数的椭圆波束排布为代表的不规则波束排布,将成为高通量卫星覆盖区域规划和系统设计的主要趋势。High-throughput satellites have become an important development trend in the domestic and international fields of satellite communications.As a key technique in the design of high-throughput satellite system,the multi-beam layout technique is closely related to users’needs,and is crucial to improve the matched capacity and reduce the cost of designing and manufacturing a satellite.According to the characteristics of the beam layout,the technology is classified into regular layout and irregular layout,and the recent advances on multi-beam layout techniques for high-throughput satellites are systematically summarized,including regular beam layout method based on region partitioning,and irregular beam layout method based on circular beams with different sizes and elliptical beams with different parameters.According to the requirements of flexible coverage of fully-flexible satellites,the cost-effective system design and the development of GEO high-throughput satellites,the development trend of multi-beam layout technique of high-throughput satellites is analyzed and inferred.For example,based on the fine-granularity user-level requirements,irregular beam layout represented by circular beam layout with different sizes and elliptical beam layout with different parameters will become the main trend of coverage planning and system design for high-throughput satellites.
