为了精确计算破片的着靶点参数，提出了一种仅对破片进行一次枚举即可获得所有着靶点参数的计算模型。在该模型中，采用考虑了速度衰减的射线法来描述破片轨迹。通过对模型的分析，得到了对应于单个破片与目标面之间三种运动关系的三种解的存在条件。以钢质破片为例，定量讨论了战斗部/目标交会参数以及破片速度衰减系数对着靶点参数的影响。结果表明，着靶点参数对目标速度和破片静止速度敏感，而对导弹速度不敏感。
To calculate hitting point parameters of fragment accurately,a calculation model was proposed to get all hitting point parameters by numerating fragments only once.In this model,the shot-line technique,which took the velocity fade into account,was adopted to describe the fragment trace.Three kinds of existence conditions of solutions,which were corresponding to three kinds of motion relationship between single fragment and target face,were obtained by analyzing the model.Taking the steel fragment for an example,the effects of warhead/target encounter parameters and fading coefficient of fragments velocity on hitting point parameters were discussed quantificationally.Results show that,the hitting point parameters are sensitive to target velocity and static fragments velocity,but insensitive to missile velocity.
