Aiming at the problems of the existing holistic kinetic models of chaff cloud,such as the complicated algorithm, the analysis for mature chaff cloud and the suitable for low speed chaff,the holistic kinetic model of chaff cloud suited for high speed chaff is proposed.Firstly the force analysis of some high speed chaff at the border of chaff cloud was carried out,secondly the chaff's position at any time was computed according to the force analysis result,finally the holistic kinetic performance at any time was obtained by ellipsoid surface fitting of the chaffs'position at any time.The simulation analysis shows the chaff cloud is ellipsoidal,the holistic kinetic parameters can be computed by the proposed model,and the simu-lation result of some parameters is consistent with the experiment result in the other references.%针对现有箔条云整体运动模型存在着算法复杂、只能分析成熟箔条云和只能适应箔条低速运动等问题，提出了适用于箔条高速运动的箔条云整体运动模型。该模型仅需对箔条云边界处若干根高速箔条进行受力分析，然后计算这若干根箔条任意时刻的位置，最后通过椭球曲面拟合得到任意时刻的箔条云整体运动性能。仿真分析表明箔条云呈椭球状，通过该模型可计算得到箔条云整体运动参数，并且有些参数的仿真结果与其他文献实验结果相一致。
