摘　　要：给出了射频掩护雷达的两种基本波形,对紧贴式射频掩护波形的抗瞬时测频性能和数字射频存储性能进行了分析,针对上述低截获概率(LPI)性能,设计了3种改进应答式干扰方法:样本预存储干扰、间歇采样干扰和信道化前沿循环复制干扰,分别对3种应答式干扰进行了干扰设计、主要参数设定和工程应用的分析。This paper provides two basal waveforms of radio frequency(RF)-screen signal radar,an-alyzes the anti-IFM(instantaneous frequency measurement) capability and anti-digital RF memory (DRFM) capability of cling RF-screen signal waveform,aiming at the above-mentioned low propability intercept(LPI) performs nee,desig ns three improved transponder jamming methods: sampleprestoring jamming,interrupted-sampling repeater jamming and channelized frontier cycle replica-tion jamming,analyzes the jamming design,main parameter setting and engineering application for three transponder jamming methods respectively.
