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. |
