| 摘 要： | 针对有源加性复合干扰,研究了基于相位扰动原理的干扰抑制方法。在结合LFM信号特征的基础上,对雷达发射信号的前后脉冲分别附加近似正交的扰动相位,再通过与前一脉冲重复周期相应的匹配滤波器将复合干扰中的欺骗干扰成分加强,并对脉冲压缩结果加以"惩罚",最后采用匹配滤波逆运算恢复出目标回波信号。

| Abstract: | According to the active additive compound jamming, an algorithm based on the phase-perturbed theory is studied. Combined with the characteristics of I.FM signal, the jamming can be restrained by changing the radar transmit signal to Slope-Varying LFM （SV LFM）, and the pulse match filter is used to strengthen the cheat jamming signal. Then the results of pulse compression is given a ＂punish＂, and finally the echo signal can be restored by the previous pulse match filter. |
