摘要
为实现对高威胁雷达精确有效的侦察干扰,文章提出了一种基于数字信道化的数字射频存储器(DRFM)设计。文章首先分析了数字信道化和DRFM一般实现方法,利用数字信道化频域分解能力,设计了数字信道化子带卷积干扰的DRFM系统,此系统增强了雷达信号选取与去噪能力,实现快速匹配实施有效干扰,以此技术为基础的仿真结果证明了其精确干扰的有效性。
A Digital radio frequency memory(DRFM) design based on digital channelization is used to realize accurate and effective reconnaissance and jamming against high threat radar. Firstly, the common way of digital channelization and DRFM is analyzed. The DRFM system with digital channelization sub-band convolution jamming is designed to improve the radar signal detection and denoising capabilities, while the effective jamming signals are generated by a quickly matching method. The accurate jamming techniques has been simulated and proved effective.
