质心干扰与切割效应探讨

针对无源质心干扰反导作战过程中箔条云和舰艇作为面目标考虑的情况,根据波束线宽变化确定的质心效应规律对其进行了定量分析,探讨了一种被称为切割效应的质心转移过程,通过计算舰艇和箔条云对导弹视场角、距离的变化,判断了目标和箔条云的切割程度及先后顺序,可推断出质心干扰成功或失败,同时为舰艇指挥员正确使用质心干扰防御反舰导弹提供了理论依据。

Discussion on Centroid Jamming and Cutting Effect

In the view of the case that the chaff cloud and naval vessel are taked as surface target in the course of passive centroid jamming during anti-missile operation,this paper quantitatively analyzes it based on the law that is determinated by changes of beam linewidth,probes into a process of centroid transition that called "Incised Effect",estimates the cutting degree and priority between target and chaff cloud through the changes of view angle and distance.We can infer whether the centroid jamming is successful or not,and at the same time it can supply theoretical basis for commanders in naval vessel to use centroid jamming correctly during defending anti-ship missile.
