摘要:
针对空空宽带高速通信的需求,设计了小型化机载激光通信系统。仿真分析了300 km、2.5 Gb/s无线激光链路性能,并通过运动仿真台模拟机动环境测试了系统的跟踪与通信性能,其中粗跟踪误差为533.2 μrad(1σ),精跟踪误差为3.6 μrad(1σ),测试数据传输240 s,通信误码率为2.82×10-9。仿真与实验验证了该系统用于远距离空空无线激光通信的可行性。

Abstract:
A miniaturized laser communication terminal is designed for airborne high speed communication.The laser link with the communication distance of 300 km and the data rate of 2.5 Gb/s is simulated.The field experiment is also executed to test the actual link performance.The experimental data reveals that the coarse and fine tracking error(1σ) is 533.2 μrad and 3.6 μrad,respectively.The experiment lasts for 240 s and the system's bit error rate is 2.82×10-9.Simulation and experimental test demonstrate the feasibility of the designed terminal for long distance and high speed airborne laser communication.
Key words:  airborne wireless laser communication  fine tracking  link simulation  miniaturized terminal
