大气层高层功能拦截器侧窗定向方位研究

大气层高层作战的动能拦截器多采用侧窗探测的结构布局,侧窗定向方位对其拦截效果有重要的影响,但定向方位的选择却受诸多因素制约.在一定理想化假设的基础上,研究了末段交战过程中视线转率的变化规律,从理论上分析了由侧窗定向产生的攻角对拦截结果的影响,得到了只考虑气动力影响下的最佳定向方位;然后综合考虑气动力、轨控系统、姿控系统的影响,给出了不同作战高度下侧窗定向方位的选择方法.数字仿真结果表明,此种方法能够满足侧窗探测的要求,且在大多数情况下只需一次定向即可完成拦截.

Study of Side Window Orientation of Kinetic Kill Vehicle Operating in Higher Atmosphere

A side window is usually adopted by the kinetic kill vehicle(KKV) operating in higher atmosphere as a basic layout.The engagement result is gravely influenced by the side window orientation which involves many factors.On the basis of some ideal hypothesis,the regularity of the line-of-sight variation rate is investigated,and the effect of the attack angle induced by the orientation is analyzed theoretically.Consequently,the optimal direction of the side window orientation is educed as the aerodynamic force ...
