| 摘要: |
| 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。 |

| Abstract: |
| This paper deseribes in detail the features of foreign next generation
military combat radios and its new concept and techniques, which of them mainly
include direct digital synthesis, spectrum-spreaded digital modulation, high-speed
modem, ALE, LQA, the Skyhopper adaptive FH and adaptive frequency management.
A new generation ECCM epuipment developed by the new techniques can efficiently
deal with enemy's interference, direction finding and interception activities and solve
nature interference, multipath effect and overcrowded spectrum.
Finally, the effort direction at present is pointed out in the paper, this is:
a. establishing norms combat radio systems among allied forces;
b. establishing interoperability among their tactical frequency-hopping communica-
tion nets (interface circuits);
c. effective communication management. |
