车载激光通信技术研究与试验

Research and Test of Vehicle-mounted Laser Communication

为解决军队战场环境下的动平台保密通信,对车载激光通信技术的可行性进行了研究,先对车载激光通信系统的应用场景和基本原理进行调研,根据指标要求完成车载动平台系统总体设计,为验证设计正确性以及车载激光通信可行性,并针对动平台的震动,采取惯性稳瞄技术保证视轴在惯性空间中稳定。最后,分别在不同大气能见度、不同通信距离条件下,对通信误码率进行监测,得到车载激光通信试验样机能够实现15km以内、100mbps的近地面激光通信的结论,验证了车载激光通信的可行性以及设计方案的正确性,可用于未来陆军战场的保密通信,同时也为以后的原理样机改进提供依据。

In order to verify the feasibility of in vehicle laser communication technology, the application scenarios and basic principles of vehicle mounted laser communication system are researched. According to the index requirements, the overall design of the system is completed and field experiments are carried out. Under different atmospheric visibility and different communication distance communication error rate, to evaluate the communication quality and to detect and analyze the mast sloshing, the vehicle laser communication prototype was completed to achieve near-surface laser corn munieation within 15km and 100mbps. The feasibility and correctness of the design scheme in vehicle-mounted laser communication were verified. The principle for the improvement of the prototype was provided in the future.
