摘　　要：箔条质心干扰是载机应对来袭导弹的一种重要的自卫手段,对于保护载机免受空空导弹及面空导弹的打击具有重要意义。在对箔条云团进行球形均匀建模的基础上提出一种利用"切割因子"对"切割效应"进行数值分析的方法。通过对箔条云、载机、导弹和波束的建模,给出了一种机载箔条质心干扰的仿真模型,最后利用此模型分析了箔条弹的投放角及箔条云扩散速率对干扰效果的影响。As an important method to protect airplane from attacking from missiles,chaff centroid jamming plays an important role.Provided that the chaff cloud is sphere and chaffs distribute uniformly in it,a numerical calculation method was presented to calculate the reduction of RCS of chaff cloud due to the effect of ＂incising＂,and a new method was given to simulate the dynamic course based on modeling of chaff cloud,aircraft,missile and beam.With this method,the impact of the optional throwing angles and diffusing velocity of chaff cloud on the effect of jamming were analyzed.
