第4代短波自动建链技术及其抗干扰技术进展

The Development of High Frequency 4G ALE Anti-jamming Technologies

短波天波通信窗口随电离层的变化(时间)而变化,因此在数据传输前对通信效果动态评估,自动选择最优频点建立链接的建链技术成为短波电台的标配,而自动建链(Automatic Link Establishment,ALE)的性能也近似决定了短波通信的效能。首先阐述了短波通信建链技术及其抗干扰性发展,其次围绕外国军队的4种第4代短波自动建链(4G-ALE)协议及其抗干扰机制进行了阐述分析,为我国建设支持短波宽带通信波形的4G-ALE机制提供借鉴。

The HF(High Frequency)communication window varies with the ionosphere(time).The technology of dynamically evaluating the communication effect before data transmission,and then autonomously searching the best frequency point to establish a link becomes the standard configuration of HF radio stations,and the performance of ALE(Automatic Link Establishment)also approximately determines the performance of HF communication.This paper first focuses on the HF communication link establishment and its anti-jamming development,and then analyzes 4 kinds of abroad HF 4G-ALE protocols and their anti-jamming mechanisms.It is expected that this research can promote the development of HF 4G-ALE wideband communication system.
