摘　　要：毫米波制导雷达具有很高的跟踪精度和分辨率,箔条在对其进行质心干扰过程中,效果受切割程度的影响较大。对飞机、箔条云和导弹分别建模,在考虑跟踪波束对飞机或箔条云"主动"切割的基础上,从几何学和运动学的角度深入研究了箔条切割效应的具体过程并加以仿真,得到了较为准确的质心运动轨迹,比较分析考虑切割效应与否时质心运动的区别,得出了相应的结论:箔条对毫米波制导导弹进行质心干扰时,切割效应很大的影响了质心运动的具体轨迹,从某种程度上决定了质心干扰成功与否。Millimeter guided radar has a good tracking accuracy and resolution. In the process of chaff centroid jamming against missile, and the effect of jamming was highly affected by the degree of the incision. The models of plane, chaff cloud and missile were built, and on the consideration of tracking beam＇s initiative incision to plane or chaff cloud, the detailed process of chaffs incision impact was specifically researched and simulated from the angle of geometry and kinematics, through which the more correct moving track of centroid could be gotten. Comparing and analyzing the differences whether the incision effect was considered, the conclusion could be summarized as follows： When chaff centroid jamming is against millimeter guided missile, the incision effect affects the centroid＇s moving track a lot, and to some extend, it decides whether the centroidjamming succeeds.
