摘　　要：针对空空导弹拦截低空掠海飞行目标时命中率较低的问题,采用C++语言对某型中远距空空导弹进行了五自由度弹道仿真建模,设计了目标运动、气体动力学、发动机推进、弹体运动学、导引头、制导、旋转、飞行控制等8个模块,以迎头攻击为基本条件,对不同初始条件下的导弹弹道进行了仿真计算,得到了导弹的弹道轨迹及部分姿态信息.重点分析了导航增益对脱靶量的影响以及发射距离、发射高度等初始条件对仿真弹道以及遇靶时导弹姿态、末制导雷达开机时导引头波束擦地角的影响,仿真结果可用于指导该型空空导弹拦截低空目标的作战使用问题.Aiming at the problem of low hit rate of air-to-air missiles intercepting low-altitude sea-skimming flying targets,a five-degree-of-freedom trajectory simulation modeling for a certain type of medium-long range air-to-air missiles were carried out by using C++language.The 8modules including target motion,aerodynamics,engine propulsion,missile body kinematics,seeker,guidance,rotation,flight control were designed.Taking head-on attack as the basic condition,the missile trajectory under different initial conditions was simulated,and the trajectory and the part of the attitude information were obtained.The effects of navigation gain on missed distance,and initial conditions such as launch distance and launch height on simulated trajectory,missile attitude at encountering the target and seeker beam grazing angle at opening the terminal guidance radar were mainly analyzed.The results can be used to guide the operational application of air-to-air missiles intercepting low-altitude targets.
