摘要:

为了研究弹道导弹及其诱饵的运动规律,分3步设计了弹道导弹主动段飞行程序。根据弹道导弹在不同运动阶段的受力情况,充分考虑大气阻力、摄动力等因素,在地心惯性坐标系下构建了包含弹道导弹主动段、自由飞行段、再入段的全弹道运动模型,并对弹道导弹的诱饵释放过程进行建模,建立了弹道导弹弹头及诱饵的运动方程组。利用该模型对携带4枚诱饵、两级火箭助推的弹道导弹进行了仿真,并分析了飞行过程中弹道导弹弹头和诱饵飞行高度、速度、倾角、加速度等随时间的变化规律。仿真结果表明,该模型能够全面准确地反映弹道导弹在几个不同运动阶段的运动特征。

Abstract:

In order to study the motion law of ballistic missile and decoy, the flight program of ballistic missile in the active phase is designed in three steps. According to the force condition of ballistic missile in different motion stages, fully considering the factors such as atmospheric resistance and perturbation force, the full ballistic motion model including the active phase, free flight phase and reentry phase of ballistic missile is constructed in the geocentric inertial coordinate system, and the decoy release process of ballistic missile is modeled, and the motion equations of ballistic missile warhead and bait are established. The model is used to simulate the ballistic missile with four decoys and two-stage rocket boost, and the variation laws of the flight height, velocity, inclination and acceleration of the ballistic missile warhead and decoy with time are analyzed. The simulation results show that the model can fully and accurately reflect the motion characteristics of ballistic missile in several different motion stages.

Key words: ballistic missile, modeling and simulation, trajectory, decoy, motion trajectory
