摘　　要：Link-22是美国(包括北约)国家近年来提出并重点发展的一种先进的数据链系统,其作为能够替代Link-11,弥补Link-11数据链不足,且可以与Link-16进行相互补充。本文在分析Link-22数据链系统配置及其报文结构的基础上,针对Link-22数据链通信系统在超视距,干扰复杂,通信条件恶劣的情况,提出并设计了波形结构,收端的盲信号检测算法、跳频抗干扰技术、基于频谱感知的速率自适应技术以及基于时变多径环境下的RLS信道估计技术,对关键原理进行了阐述和分析,可为数据链领域的相关研究工作提供参考。Link-22 is an advanced data Link system proposed and developed by the United States(including NATO)countries in recent years.It can replace Lin K-11,make up for the deficiency of Link-11 data Link,and as a complement of lin K-16.Based on the analysis of the Link-22 data Link system configuration,the structure of the message,and the communication condition of over-the-horizon,complex interfere,we proposed and designed the structure of Link-22 waveform structure,the blind signal detection algorithm,the frequency hopping anti-jamming technology,speed adaptive technology based on spectrum sensing and the RLS channel estimation based on time-varying multipath environment,which can provide reference for related research work in the field of this data link.
