摘要
弹道导弹大气层外飞行时间长且弹道固定,易被敌方预测和拦截。因此提出一种最优脉冲变轨方法:首先,建立了导弹单脉冲作用下的机动变轨模型;其次,基于对模型的分析,选取机动变轨所需能量和变轨后飞行剩余时间的加权为性能指标,并利用遗传算法进行寻优,搜索出满足性能指标最优的机动变轨点。最后,通过仿真验证了该最优脉冲变轨方法的有效性。
Ballistic missile has a long time flight in the exoatmosphere and its trajectory is fixed, so it is vulnerable for ene- my prediction and interception. The thesis presents a method of optimal impulse orbit transfer. Flatly, establish the orbital maneuver model under the action of single impulsive effect. Secondly, according to the analysis of the model, the needed en- ergy of orbital maneuver and the rest time after orbital transfer will be selected as performance index, in order to find the or- bital maneuver point where it can satisfy the performance index the genetic algorithm was used to optimize. In the end, it is improved that the method of optimal impulse orbit transfer is efficient through simulation.
