舰载跳频通信系统抗引导式跟踪干扰分析

摘要

复杂电磁环境下,跳频通信已成为舰艇战术通信的重要手段之一.研究舰载跳频通信系统抗干扰的理论,寻求可行的抗干扰方法,对保障通信联络顺畅具有现实意义.通过分析引导式跟踪干扰的原理,结合短波、超短波和微波的传播特点,明确了对跳频通信实施引导式跟踪干扰的条件,阐述了在实际应用中易产生混淆的情况,给出了提高跳频通信抗引导式跟踪干扰效能的几种对策.为正确应用跳频电台,增强海上编队通信对抗作战效能提供了参考.%Under the complex electromagnetic circumstances, frequency hopping system is one of naval vessel's tactics communication tools. It is significant for us that researching on the theory of anti-jamming and seeking for some workable anti-jamming methods to ensure that the signal communication is unhindered. By analyzing the theory of directed tracking jamming, considering characteristics of HF, VHF and microwave electromagnetic propagation, this paper presents the requirements of directed tracking jamming,explains the circumstances that easily be confused in practice. It is emphatically discussed on how to enhance the performance in anti-jamming on the shipboard frequency hopping system. What the paper research on will be helpful for guiding the proper application of frequency hopping radios to enhance operational effectiveness of communication countermeasure for formation of ship.
