基于直升机中继转发的卫星应急通信的研究

Research on Satellite Emergency Communication Based on Helicopter Relay Forwarding

加强卫星通信在应急通信中的稳定性,如何克服复杂环境实现“山中通”“动中通”一直是卫星通信的研究热点,文章提出的基于直升机中继转发的卫星应急通信提出了一条很好的解决思路。通过对转发器,组网技术,抗旋翼遮挡等关键技术的研究,实现了卫星通信终端脱离卫星而通过救援直升机进行组网或者中继通信。

It has always been a research hotspot in satellite communication of how to enhance the stability of satellite communications in emergency and how to achieve"satcom in the mountain"and“satcom on the move"in a complex environment.Through the study of key technologies such as transponders,networking technology,and anti-rotor occlusion,this paper presents a solution of satellite emergency communication,that is,to network or relay communicate based on rescue helicopters.
