摘要: 欺骗干扰是一种常用的雷达干扰技术,提出了一种对抗单脉冲雷达的欺骗干扰机设计新方法。在分析欺骗干扰信号特性基础上,基于压缩感知(CS)框架和数字射频存储(DRFM)技术,根据线性调频(LFM)信号在分数阶傅里叶域的能量聚集特性,设计了压缩感知框架下的DRFM以产生角度欺骗干扰信号;通过控制干扰信号强度产生角度拖引和闪烁干扰以实现对单脉冲雷达角度跟踪的有效干扰。仿真实验结果表明,干扰机能够产生良好的角度欺骗干扰信号,通过干扰信号强度控制能够产生稳定的角度拖引和闪烁干扰。

Abstract: Deceptive jamming is a common radar jamming technology. This paper presents a novel deception jammer against monopulse radar. First, the characteristics of angle deceptive signal is analyzed. Then, according to energy aggregation properties of the linear frequency modulation (LFM) signal in fractional domain, a digital radio frequency memory (DRFM) under compressed sensing (CS) framework is proposed in order to generate angle deceptive jamming signal. In order to achieve effective jamming against the monopulse radar tracking system, the angle pull-off jamming and glint jamming achieving method is considered by controlling the power of jamming signal. Simulation results show that origin signal can be recovered with the proposed method very well, and the jammer can achieve a stable angle pull-off and blink jamming.

Key words: deceptive jamming, fractional Fourier transform, digital radio frequency memory (DRFM), compressed sensing (CS), angle jamming
