摘要
为提高抗干扰能力,雷达采用射频掩护信号对抗有源干扰机。分析射频掩护信号的产生机理和工作波形,以及射频掩护信号对雷达有源干扰机中测频接收机、信号处理机、数字射频存储器及脉冲行波管发射机的影响,从而给出雷达有源干扰机对抗射频掩护信号的方法。
In order to increasing the anti-jamming ability, the radar antagonizes active jamming by adopting the radio frequency-screen. The fountainhead and working wave are analyzed. The influence on the frequency- measuring receiver, signal processor,digital radio frequency memory（DRFM）, and pulse TWT transmitters of radar active jamming are construed. Finally, the method of radar active jamming antagonizing the radiofrequeney-sereen is presented.
