Research on Countermeasures of Intrapulse Strong Signal Detection Technology for Anti-radiation Seeker

针对主瓣持续照射雷达的有源诱饵,提出了一种脉内强信号检测抗诱偏措施;首先理论分析了诱饵对反辐射导引头测向的影响;其次,利用三诱饵三维空间诱偏误差公式定量计算了雷达主瓣持续照射时的诱饵诱偏误差;最后给出了脉内强信号检测技术的实现方法;由理论分析及定量计算结果可知,采用脉内强信号检测技术可以有效对付主瓣持续照射雷达的有源诱饵,是一种合理可行的抗诱偏技术。

For the active decoy of mainlobe irradiate, this paper proposed countermeasures of intrapulse strong signal detection against decoy. Firstly, this paper made a theoretical analysis on the effect of decoy against anti--radiation seeker orientation; Secondly, using three decoys three dimensions error formula to make a quantitative calculation of decoy inveigles error under the condition of mainlobe irradiate radar; Finally proposed intra--pulse strong signal detection technology. According to theoretical analysis and quantitative calculation, the intra --pulse strong signal detection technology can deal with active decoy of mainlobes of radar irradiate, and this technology is a reasonable and viable decoy countermeasures.
