摘要
PD雷达是一种可对运动目标进行检测和跟踪的新体制雷达，对其速度跟踪系统进行欺骗干扰可有效破坏雷达对目标的跟踪。DRFM是一种高速数字存储器件，它所产生的波形是雷达信号的完全复制，使用数字单边带调制器，可在DRFM输出信号上附加一定的多普勒频移，实现对PD雷达的速度欺骗干扰。
PD radar is a new kind of radar that can track and detect the moving target. The deception jamming technique can jam the velocity tracking system of PD radar effectively and make the radar can＇t track the target. DRFM is a kind of high speed digital memorizer. It can generate the copy of the radar signals. Meanwhile, using the digital single - sideband modulator can add a Doppler shift - frequency in the output of DR.FM, which will help to achieve the aim of velocity deception jamming.
