本文较系统地介绍了外军下一代战斗网电台的特点及其所采用的新概念、新工艺、新技术,其中主要包括:直接式数字频率合成法、扩展频谱数字调制、高速调制解调器、自动链路建立(ALE)、线路质量分析(LQA)、天跳器自适应跳频、自适应频率管理等。利用这些技术研制的新一代ECCM设备,能有效地对付敌方的干扰、测向和窃听活动,以及自然干扰、多径效应和频谱拥挤等问题。文章最后指出,目前努力的方向是:①在同盟军内建立各国统一的战斗网电台规范;②在各国的战术跳频通信网间建立互通性(接口电路);③建立有效的通信管理能力。
This article systematically introduces the characteristics of the Next Generation Combat Network Radio and the new concepts, new techniques and new technologies adopted by the next generation of Combat Network Radio stations. The main contents include direct digital frequency synthesis, spread spectrum digital modulation, high speed modem, automatic chain Road Establishment (ALE), Line Quality Analysis (LQA), Hopper Adaptive Frequency Hopping, Adaptive Frequency Management. The new generation of ECCM devices developed using these technologies effectively deal with enemy interference, direction finding and wiretapping activities as well as natural interference, multipath effects and spectrum congestion. Finally, the article points out that the direction of current efforts is: (1) establish a unified national battlefield network radio standard within the Allied Forces; (2) establish interoperability (interface circuits) among tactical FH communication networks in various countries; and (3) establish effective communication management capabilities.
