Solution of Reentry Trajectory of Ballistic Missile Using Genetic Algorithm

基于弹道导弹再入段运动数学模型,提出了预定程序弹道再入突防的方法并进行了遗传算法解算突防弹道的研究。建立了以攻角随再入时间增长的变化量为编码对象的遗传算法模型并进行仿真计算。仿真结果表明,该算法能够实现预定程序再入弹道快速高精度的解算,具有工程的应用价值。

Based on the mathematic model of reentry movement of ballistic missile, the method of adopting preprogram trajectory to penetrate was established and solution of the penetration trajectory using genetic algorithm was studied. The genetic algorithm model which took the angle of attack changing along with reentry time increasing as the object of coding was introduced and the simulation was continued. The simulation result shows genetic algorithm can carry out the accuracy result of reentry trajectory solution with high speed, this algorithm can make the choice for application.
