| Abstract: | 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. |
