摘要
文章提出了采用宽带DAC实现直接数字频率合成器的方法,利用随机函数生成噪声模型,采用FPGA控制DAC,从而使得雷达噪声干扰信号的带宽、频率、相位、幅度、谱型和样式任意可编程,可以有效对雷达实施噪声干扰。
This paper proposes a method of implementing direct digital synthesizer adoptting broad band DAC.Building noise model by using of random function.Commanding DAC via introducing FPGA.As a result,bandwidth,frequency,phase,amplification,spectrum types and modes of Radar noise jamming signal are programmable at discretion,which implements effective noise jamming on the radar.
