一种抗反辐射导弹诱偏系统时序设计及验证

Timing Design of Decoying System for Anti-ARM and Verification

有源诱偏系统可以极大减小雷达受辐射导弹攻击的概率,其诱饵信号与雷达信号的时序关系是直接影响诱偏效果的关键因素。针对某四点源非相干诱偏系统信号的时序关系做了相关分析,采用了三诱饵信号源覆盖雷达信号合成诱饵信号方法,对四点源信号的时序进行了设计与优化。利用某型号制导雷达的四点源诱偏系统开进行了反辐射效果验证,分析试验数据可知:该四点源时序设计与优化方法有效可行,提高了对反辐射导弹诱偏效果。

Active decoying system can protect radar from anti -radiation missile （ARM） attacking effectively. Tim- ing relation between decoy signal and radar signal is a critical factor which would affect decoying effect directly. Timing of signal of fourpoint source non - coherent active decoying system is analyzed. By using three decoy signals which can cover radar signal to form decoy signal, timing of fourpoint source signals is designed and opti- mized. Anti - ARM effectiveness is verified by using a four - point source decoying system of a guidance radar ; data analyzing indicates that, design and optimizing method of timing of four - point source is effective and feasible, which is able to improve decoying effect against ARM.
