战术导弹防御中的拦截交会角约束研究

由于拦截器侧向发动机纠偏能力的限制及TBM的初始位置误差的影响,拦截交会角需要满足一定的范围才能命中目标.本文研究了战术导弹防御的拦截交会角约束问题,提出了一种运动学几何分析方法,推导了TBM的初始位置误差引起的横向偏差与拦截交会角的解析关系,分析了拦截交会角对末制导段纠偏的影响,确定了可命中目标允许的拦截交会角范围.通过仿真计算和分析,论证了该方法的有效性.

Research on Constraint of Intercepting Rendezvous Angle of Intercepting Tactical Ballistic Missiles

This paper investigates the constraint of intercepting rendezvous angle.In order to intercept TBM successfully,the range of intercepting rendezvous angle is limited while the effective intercepting rendezvous angle is affected by the ability of the side engine of the interceptor and the initial position error of TBM.A kinematic geometrical method is presented.Then with the new method the analytical relation between the initial position of TBM and intercepting rendezvous angle is deduced.The impact of intercepting rendezvous angle on error correction during last phase of control and guidance is also analyzed.With the above work the effective rang of intercepting rendezvous angle can be determined ultimately.Based on simulation of a typical TBM,the validity of this approach is proved.
