目前国际上点对点激光通信技术已较为成熟,但多平台间组网通信问题仍未能解决。提出了一种新型组网通信光学天线设计方法,可实现多点间同步双工激光通信。分析了光学天线原理,并通过仿真建模验证了设计理论,给出了光学天线的结构设计和工作模式,最后采用数学最优控制算法推导出多组光学天线多平台动态、双工通信的工作范围,当旋转抛物面开口为300 mm时,能使方位角为360°,俯仰范围为90°以上。并针对GEO(高轨道卫星)—GEO—OGS(光学地面站)间的组网通信要求进行了光学天线的初始化设计,对推动激光通信技术实现大范围宽领域应用具有重要意义。
At present, the peer-to-peer laser communication technology is relatively mature in the world, but the problem of network communication among multiple platforms still can not be solved. A new design method of network optical communication antenna is proposed, which can realize multi-point synchronous duplex laser communication. The principle of optical antenna is analyzed, and the design theory is verified through simulation. The structure design and working mode of the optical antenna are given. Finally, the mathematical optimal control algorithm is used to derive the multi-group optical multi-platform dynamic and duplex communication Range, when the rotating parabolic opening is 300 mm, the azimuth can be 360 ° and the pitch range is 90 ° or more. The initial design of the optical antenna for the GEO (high orbiting satellite) -GEO-OGS (optical ground station) network communication requirements is of great significance in promoting the wide range of wide-area applications of the laser communication technology.
