多通道数字干扰源设计与实现

Design and Realization of Multichannel Digital Jamming Source

为应对日益复杂的电子战环境,采用多通道数字干扰源技术,一部发射机可同时发射多个干扰信号,从而实现同时对多部雷达实施压制式和欺骗式干扰。针对电子对抗领域中干扰源的实际应用,阐述了多通道数字干扰源的数字模型,设计了一种大带宽数字信道化干扰源的技术方案,并用MATLAB进行了原理仿真,最后采用现场可编程门阵列(FPGA)给出了该技术的工程实现方法,实际测试结果显示:所设计的数字干扰源具有瞬时带宽大、能对多部雷达信号进行压制式和欺骗式干扰等特点。

For antagonizing increasingly complicated electronic warfare circumstance, the technology of multi-channel digital jamming source （DJS） is adopted. A transmitter can transmit multiple jam- ming signals synchronously, thereby blanket jamming and deception jamming are performed to mul- tiple radars synchronously. Aiming at the practical application of jamming resource in electronic countermeasure field,this paper expatiates the digital model of multi-channel digital jamming re- source, designs a technology project of broadband digital channelized jamming resource,and uses MATLAB to perform the principle simulation, finally uses field programmable gate array （FPGA） technology to give the engineering realization method of the technology. The practical test result shows that the designed digital jamming resource has characteristics of wide band and can perform blanket jamming ＆ deception jamming to multiple radars signals,etc.
