抗干扰技术分析

Analysis on Anti-jamming Technology

抗干扰技术是现代信息战争的支柱,必须研究有效的抗干扰技术以对付日益严重的干扰威胁。介绍了干扰和抗干扰的几种方式,给出了扩频、自适应天线、自适应干扰抑制、纠错编码+交织技术、自适应功率控制和自适应选频等多种抗干扰技术,论述了电调滤波技术抗干扰的工作原理,重点分析了电调滤波器的实现及在抗干扰通信中的优点,指出了固定宽带滤波器的不足,探讨了未来电子对抗的发展方向。

Anti-jamming technology is the mainstay of modern information war.The effective anti-jamming technologies need to be developed against more and more serious jamming threats.Some jamming and anti-jamming methods are introduced,and several anti-jamming technologies such as spectrum spreading,self-adaptive antenna,adaptive interference suppression,error correction code and interleaving,self-adaptive power control and self-adaptive frequency selection are put forward.The operating principle of anti-jamming of electrically tunable filtering technology is discussed.The implementation of electrically tunable filter and the merits in anti-jamming communication are analyzed emphatically,and the shortcoming of fixed wideband filter is pointed out.In the end,the development direction of future electronic counter measure is explored.
