摘要/Abstract

摘要： 首先分析了噪声干扰以及基于下降沿触发式的相参干扰在对抗雷达射频掩护中的不足,着重在干扰反应时间及频率捷变信号适应性等方面展开研究,指出了基于下降沿触发式的相参干扰反应时间长、易被操作手识别,且无法适应频率捷变信号等缺陷。为此,提出了基于脉冲簇识别的干扰方法,分析了该方法在对抗雷达射频掩护中的优势,并进行了仿真,验证了其有效性。

关键词: 射频掩护, 下降沿触发, 脉冲簇识别, 威胁库匹配, 数字射频存储, 干扰反应时间

Abstract: First of all,the deficiencies of noise interference and coherent interference based on drop edge trigger in radar radio frequency(RF) cover are analyzed, the research is focused on the interference response time and frequency agility signal adaptability. It is pointed out that the response time of coherent interference based on drop edge trigger is long, which is easy to be recognized by the operator and impossible to adapt to frequency agility signal. Therefore, the jamming method based on pulse cluster identification is proposed. The advantage of this method in anti-radar RF cover is analyzed, and its effectiveness is verified.

Key words: radio frequency (RF) cover, downside triggers, pulse cluster identification, threat libraty matching, digital RF memory, interference reaction time
