摘要
DRFM移频干扰是针对LFM脉冲压缩雷达等一些新体制雷达所提出的新型干扰技术,其干扰信号与雷达发射信号具备较强的相干性、干扰样式的多样性及灵活性,导致雷达难以利用现有的抗干扰技术进行反干扰。此文从分析干扰信号与目标回波信号参数的不同之处入手,提取出真实目标回波信息,较好地实现了抗移频干扰。
DRFM Frequency-shift interference is a new interference technology proposed focusing on LFM pulse compression radar and some new system radars. The signals of DRFM frequency-shift interference have strong chherences with radar transmit signals. The varieties and flexibilities of interference modes make radars not antijamm by using existing technologies. Based on the differences of parameters between inteerference signals and target echo signals, the echo information of real targets are obtained to realize suppressing frequency-shift interference.
