摘　　要：针对对空导弹末制导段多采用比例式制导,而防御对空导弹多采用平台自卫式干扰机的情况,分析了对空导弹比例式制导的控制特性及其面临的光电干扰环境,提出了一种全新的对导弹末制导段飞行轨迹简化计算方法,以及光电干扰有效后导弹的脱靶量数学模型,并据此进行干扰条件下导弹命中概率的计算分析;重点讨论了导弹不能命中目标时的边界条件,即光电干扰有效时对应的导弹姿态、距离、飞控参数等,并论述了光电干扰条件下导弹命中概率和不能命中的边界条件。据此可对平台自卫干扰装备的作战效能进行定量评估,并评价导弹导引头的抗干扰性能。The proportional guidance is often used in the terminal guidance section of surface-to-air missile,while the platform self-defense jammer is often used to defend surface-to-air missile.This paper discusses the control characteristics of proportional guidance for surface-to-air missile and the photoelectric interference environment.A new simplified calculation method for the flight trajectory of the missile in the terminal guidance section and a mathematical model for the miss distance of the missile after effective photoelectric interference are presented.Based on this,the hit probability of the missile under the interference condition is calculated and analyzed.This paper focuses on the boundary conditions when the missile cannot hit the target,that is,the corresponding missile attitude,range,and flight control parameters when the photoelectric interference is effective,and discusses the missile hit probability under photoelectric interference and the boundary conditions when the missile cannot hit the target.The study can be used to quantitatively evaluate the combat effectiveness of the platform self-defense interference equipment and evaluate the anti-interference performance of the missile seeker.
