面源红外诱饵对抗红外制导导弹干扰策略研究

Research on jamming strategy of surface-type infrared decoy against infrared guided missile

面源红外诱饵使用的过程中,合理有效的干扰策略是干扰红外制导导弹的关键,针对这一问题,通过理论分析与仿真模拟相结合得到面源红外诱饵对抗红外制导导弹的干扰策略。首先以红外成像制导导弹为例,介绍红外制导导弹的仿真模型,然后将攻击过程分为锁定前与锁定后,以命中率为评价指标,得到两个阶段下的最佳干扰策略,包括诱饵的最佳释放时机、释放间隔以及载机应采取的机动动作等。

In the use of surface-type infrared decoys,the reasonable and effective jamming strategy is the key to jamming the infrared guided missile successfully.Aiming at this problem,the jamming strategy of the surface-type infrared decoys against the infrared guided missile is obtained by combining theoretical analysis and simulation.First,taking infrared imaging guided missile as an example,the simulation model of infrared guided missile is introduced in this paper.Then,the attack process is divided into pre-lock and post-lock.At last,taking the hit rate as the evaluation index,the optimal jamming strategy under two stages is obtained,including the optimal release time of decoys,release interval and the maneuvering action that should be taken by the carrier aircraft.
