应用求解非线性规划问题的直接方法，针对一种典型的目标弹道（１０００ｋｍ） ，对一种方案反战术弹道导弹进行了总体参数优化设计研究．研究中考虑了：发动机特性参数的变化；导引头侧窗口对交汇角的限制；烧蚀问题所引起的对最大马赫数Ｍａｍａｘ的限制和末速的限制；导弹发射时机的选择；导弹的初始弹道角的选择；其它（ 如最大过载和最大攻角的限制及重力补偿等） ．研究的目的是在考虑满足各种限制的条件下，通过选择各主要参数，使拦截区最大．结果表明，通过采用混合火箭发动机方案可扩大导弹的作战空域，同时满足采用侧窗导引头所带来的限制条件．
Aiming at a typical target trajectory (1000km), a direct method of solving nonlinear programming problems is applied to optimize the overall parameters of a scheme anti-tactical ballistic missile. In the study, the following factors were considered: the change of the engine characteristic parameters; the limit of the seeker side window on the confluence angle; the limit of the maximum Mach number Mamax and the limit of the end speed caused by the ablation problem; the choice of the missile launch timing; Ballistic angle of choice; other (such as maximum overload and maximum angle of attack and gravity compensation, etc.). The purpose of the study is to maximize the interception area by considering the main parameters, taking into account the various constraints. The results show that by using a hybrid rocket engine scheme, the operational airspace of a missile can be expanded while meeting the constraints imposed by the side-window seeker.
