Airborne space laser communication system and Experiments

摘要

Airborne space laser communication is characterized by its high speed, anti-electromagnetic interference, security, easy to assign. It has broad application in the areas of integrated space-ground communication networking, military communication, anti-electromagnetic communication. This paper introduce the component and APT system of the airborne laser communication system design by Changchun university of science and technology base on characteristic of airborne laser communication and Y12 plan, especially introduce the high communication speed and long distance communication experiment of the system that among two Y12 plans. In the experiment got the aim that the max communication distance 144Km, error ＜10~(-6) (2.5Gbps) ＜10~(-7) (1.5Gbps), capture probability ＞97%, average capture time 20s. The experiment proving the adaptability of the APT and the high speed long distance communication.
