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。
Spoofing interference is a commonly used radar jamming technique, and a new design method of deception jamming jamming machine against monopulse radar is proposed. Based on the analysis of the characteristics of deception and jamming signals and based on the compressed sensing (CS) framework and the digital radio frequency memory (DRFM) technique, the energy-gathering characteristics of LFM signals in fractional Fourier domain are designed. Of DRFM to generate angle-spoofing interference signals; angle drag and flicker interference are generated by controlling the interference signal strength to achieve effective interference with monopulse radar angle tracking. The simulation results show that the jammer can produce a good angle to spoof the jamming signal, and the jamming signal intensity control can produce stable angle dragging and blinking jamming.
