摘要
结合线性调频脉压体制雷达的特点和数字射频存储技术(DRFM)的发展现状,提出了一种基于数字射频存储技术的卷积干扰生成方法,并在现场可编程门阵列器件中进行了实现。文中论述了DRFM的工作原理和卷积干扰可行的理论分析,同时给出了卷积干扰算法的实现方法。最后,通过自建的仿真试验平台进行了实验验证,并分析了试验结果。
Combine linear frequency modulation pulse compressed radar features with digital radiofrequency memory（DRFM）technology＇s evolution,a convolution jamming technique based on DRFM was introduced.It was implemented in field program gate array device.How DRFM and convolution jamming work were described by theory in the paper.How to implement in FPGA was also referred.Lastly,a test-bed was made to verify the technique and test results were analyzed.
