With the development of society and technology,phased array software radio technology has been rapidly promoted and popu-larized,and its application fields have gradually expanded from the traditional military early warning detection to meteorological detec-tion,aviation safety,unmanned drive,space detection,earth-space communication relay and so on.At the same time,the application of new methods and new systems puts forward higher requirements on the complexity of antenna beamforming algorithm,data transmission volume and low delay of beam switching,etc.Commercial applications require efficient and low-cost deployment and good scalability based on software definition.Traditional centralized beam control methods can no longer effectively meet the needs.Beamcontrol node deployment can realize the nearby beamforming operation and data processing of the RF front end of the phased array antenna by using the edge computing concept,effectively reducing the data transmission bandwidth and delay.The beamcontrol platform adopts the soft-ware reconfigurable system to adapt to the development and change of emerging fields and user needs.The principle of phased array RF front-end beam control is introduced,and a reconfigurable beam control technology based on edge computing is proposed.The embedded distributed operation and processing technology is adopted.Through modeling,simulation and calculation,it is proved that this technolo-gy can effectively improve the multi-channel data transmission pressure of phased array antenna,improve beam agility,realize function and aperture reconfiguration,and has a wide engineering application prospect.
