Satellite multi-beamforming network device and beamforming method for synthesizing tracking beams

Abstract

The invention discloses a multi-beam satellite antenna beamforming network device and a beamforming method for generating beams for tracking mobile users, including beam generation and resource allocation modules, variable coefficient beam weighting network, programmable switch array, feed source signal Synthetic network, beam mobility management and control module; programmable switch array: including multiple rows, multiple columns, switches located at the intersection of rows and columns, connecting the rows and corresponding columns in the array by closing the switch; this The invention can achieve the effect of continuous scanning of each beam of the satellite multi-beam antenna in the coverage area of ​​the system, can be independent of different communication transmission systems, and can solve complex problems such as handover required to realize cross-beam cell services in the existing fixed multi-beam satellite system mobility management issues.

Description

technical field [0001] The invention belongs to the technical field of communication, relates to satellite communication technology, in particular to a satellite multi-beam forming network device and a beam forming method for synthesizing tracking beams, which are used to generate beams for tracking mobile users. Background technique [0002] Broadband / mobile / high-speed satellite communication is a current research hotspot and industry focus. The so-called broadband satellite communication system generally refers to various high-speed satellite communication systems that carry and provide broadband Internet access services and new broadband multimedia services. The transmission rate standard generally requires that the corresponding user's maximum data rate can reach 2Mbps or higher. Broadly speaking, broadband satellite communication includes broadband mobile satellite communication (MSS) and broadband fixed satellite communication (FSS) Two types. In fact, broadband fixed...
