摘要
具有再入机动能力是现今导弹发展的主要方向,而研究机动变轨对提高导弹作战能力的作用效果,首先要在设计研究再入机动弹道的基础上开展。在建立空间再入机动弹道数学模型的基础上,从保证末速最大的要求出发,利用最优控制原理和数值分析进行了最佳再入机动弹道设计,并基于VisualC++编程软件进行仿真计算。结果表明,设计方法可行,验证了模型的正确性和所作近似的合理性。通过图例可以看出机动弹道可大大提高导弹的突防能力和生存能力,具有攻击复杂地形目标的能力。
The primary development derection of missile is to have the ability of reentry maneuver. Based on the interspace mathematical model of reentry maneuvering trajectory, according to the requirement of maximal terminal velocity, the optimal control theory and numerical analysis are used to design the optimum trajectory, and simulation is made by using Visual C ＋ ＋. The result shows that the design way is feasible, the correctness of the model and the rationality of the approximation are validated. The chart shows that the maneuvering trajectory can improve the penetrating capability and the hitting precision markedly, it also has the ability to attack the target with complex terrain.
