烟幕干扰条件下光电制导导弹命中概率计算方法

Hit Probability Calculation of Photoelectric Guided Missile Under Smoke Jamming Condition

针对当前的研究没有将烟幕对光电导引头的影响与光电制导导弹的杀伤效果关联起来的问题,提出了烟幕干扰条件下光电制导导弹命中概率计算方法。该方法以光电制导导弹为研究对象,将烟幕遮蔽对光电导引头的影响转化为对导弹散布误差的影响,运用射击效能的相关理论得出导弹命中概率。仿真结果表明,该方法可有效地计算烟幕遮蔽条件下3种光电制导导弹的命中概率,为直观地评估烟幕干扰对光电制导导弹的影响效果提供了一种方法。

Current studies do not correlate the effects of smoke on photoelectric signals and seekers with the lethality of photoelectric guided missiles.To solve this problem,a method for calculating the hit probability of electro-optical guided missiles under smoke screen jamming was presented in this paper.The method took the photoelectric guided missile as the research object, transformed the influence of smoke screen on the photoelectric seeker into the influence on the dispersion error of the missile,and obtains the hit probability of the missile by using the relevant theory of shooting effectiveness.The simulation results showed that this method could effectively calculate the hit probability of three kinds of photoelectric guided missiles under the smoke shield condition,and provided a method for directly evaluating the effect of smoke interference on photoelectric guided missiles.
