弹道导弹再入段拦截的毁伤效果评估

Battle Damage Assessment Methods in TBM Reentry Interception

从跟踪雷达的角度进行了再入段弹道导弹毁伤效果评估的研究。分析了弹道导弹在再入段遭到拦截时可能发生的2种情况,在此基础上将弹道系数引入弹道目标毁伤效果评估中,提出了基于弹道系数估计的弹道导弹再入段拦截的毁伤效果评估方法,仿真了3种弹道目标即完整弹头、弹体残骸、小碎片的弹道系数,证明了该方法在毁伤评估中的可行性。通过仿真机动变轨和碰撞变轨2种模型下的弹头运动轨迹,研究了目标机动对弹道导弹毁伤评估可能造成的影响,并得出可以避免这种影响的方法。

Battle damage assessment in TBM reentry interception is studied from the perspective of tracking radar. Firstly, the paper analyzes two kinds of circumstances when reentry TBM is intercepted. Based on this, the ballistic coefficient method is applied to TBM battle damage assessment, and a method of calcu- lating ballistic coefficient is introduced. Then a method of TBM Battle damage assessment based on ballis- tic coefficient estimation is put forward. By simulating the ballistic coefficients of three ballistic targets complete warhead, wreckage and litter pieces, the assessing method proved to be available. The influence of radar measurement accuracy on the evaluating error of ballistic coeficient is analyzed by simulation, and it comes to the conclusion that the improvement of radar measurement accuracy benefits the assessing ac- curacy of TBM battle damage. Finally, the effect of target maneuver on assessment is studied by simula- ting the warheads＂ contrails in maneuver-shifting contrail model and in collision-shifting contrail model, and the solution is summarized to avoid this effect.
