以红外制导导弹为典型代表的光电精确制导武器在军事上的广泛应用,促进了与之相应的光电干扰技术的迅速发展。如何消弱敌方红外制导导弹的攻击效果,是海军作战中迫切需要解决的问题。激光武器以其独特的性能成为对抗红外制导导弹的理想武器,为准确评估激光干扰红外制导导弹的效果,对某红外制导导弹的巡航段弹道建立了导弹运动学模型、寻的/跟踪器模型、导引处理器模型和碰撞检测模型。以脱靶量为最终输出参量进行干扰评估,同时给出了命中概率的下降情况。仿真结果表明:激光能够有效地干扰该型红外制导导弹,使其脱靶量发生大幅度变化。随着干扰距离的增大,导弹的命中概率也迅速下降。结果证明干扰时机的选取对干扰效果的好坏有着至关重要的作用。
The widespread use of photoelectrically guided weapons, typically represented by infrared guided missiles, in the military field has promoted the rapid development of corresponding photoelectric interference technologies. How to weaken the attack effect of the enemy’s infrared guided missiles is an urgent issue that needs to be solved in naval operations. In order to accurately evaluate the effect of laser interfering infrared guided missiles, laser weapon has become an ideal weapon against infrared guided missiles with its unique properties. The kinematics model, the seeker / tracker model, Guided processor model and collision detection model. Taking the miss distance as the final output parameter, the interference evaluation is performed, and the probability of hit is reduced. The simulation results show that the laser can effectively interfere with this type of infrared guided missile, making the amount of miss distance greatly changed. As the interference distance increases, the probability of missile hits also decreases rapidly. The results show that the timing of interference is crucial to the quality of the interference.
