机载空间激光通信大气附面层影响及补偿技术研究.

With the development of space laser communications technology, the atmospheric environment has a prominent effect on the airborne space laser communication, and the atmospheric boundary layer is one of the main influencing factors. To study the effect of atmospheric boundary layer on the communication, the influence of the boundary layer is discussed based on the airborne laser communications experiment and the theory of diffraction optics. The results show that the effect of atmospheric boundary layer on the space laser communications system is due to attaching a negative lens with focal length of -530 m in front of the system to cause the change of system focal length and the spot diffusion. The effect can be compensated by increasing a compensative lens in the system, and the corresponding compensation tests are carried out. The results show that the effect of the atmospheric boundary layer on the space laser communication can be compensated by optical method, and the compensation meets the requirements of space communication.
