摘要: 机载无线激光通信具有通信速率高、抗干扰能力强、保密性好、布置灵活等优点,在天地一体化高速信息网络、军用保密通信、电磁干扰环境下可靠通信等应用中有着广阔前景。为解决机载环境下激光通信光轴对准难题,通过对无线激光通信系统特点和Y-12型飞机平台特性的分析,采用粗、精两级复合跟踪方案,设计了由被动减震结合主动抑制的粗跟踪单元和电磁振镜精跟踪单元组成的机载无线激光通信对准、捕获、跟踪(PAT)系统。Y-12飞机搭载该系统开展了双固定翼飞机间远距离、高速机载激光通信试验,验证了所设计的机载无线激光通信PAT系统的跟踪性能和机载环境适应性。

Abstract: Airborne space laser communication is characterized by high speed, anti-electromagnetic interference, security and easy assignment. It has been applied in the areas of integrated space-ground communication, networking communication, military communication, reliable communication in anti-electromagnetic environment. The characteristics of airborne laser communication and Y-12 plane are analyzed for aligning the communication optical-axis on airborne platform. Two-stage tracking technology is used to design an airborne pointing, acquisition and tracking (PAT) system for laser communication , which consists of coarse and fine tracking units. The long distance communication experiment of the system carried by Y-12 planes is accomplished. The experiment proves the tracking performance and adaptability of the PAT system.

Key words: communication technology, laser communication, airborne platform, pointing, acquisition and tracking
