航空平台是天、空、地一体化立体空间网络的重要节点,建立空星、空空、空地激光通信链路是实现机载激光通信的关键。介绍了机载激光通信实验系统的组成与工作原理;进行了机载激光通信系统特殊性分析,包括大气附面层、平台随机大幅度扰动、平台高频振动、大气信道等外界约束环境对激光通信系统性能的影响以及相关抑制技术;具体介绍了飞艇-船舶间空地激光通信实验、双直升机间空空快速捕获实验以及双固定翼飞机间空空远距离激光通信的实验成果。
Aviation platform is an important node in the integrated three-dimensional space network of sky, air and land. It is the key to realize airborne laser communication to establish air-star, air-ground and space-lase laser communication links. The composition and working principle of the airborne laser communication system are introduced. The particularity of the airborne laser communication system is analyzed, including the atmospheric surface layer, the random disturbance of the platform, the vibration of the platform, the atmospheric channel and other external constraints on the laser The influence of communication system performance and the related suppression technology are introduced. The experiment of airship-space laser communication between ships and ships, the experiment of air-space rapid trapping between two helicopters and the experiment of air-to-space and long-distance laser communication between two fixed-wing aircraft are introduced in detail.
