质心干扰的应用研究

Research into The Application of Centroid Jamming

在雷达无源对抗中,通过发射箔条弹对敌方雷达形成干扰是一种常见的方式。详细介绍了质心干扰的原理及其过程,并建立了干扰地空导弹的模型,计算出飞行员在满足对导弹实现质心干扰的前提下应发射箔条弹的最少数量,提高箔条弹的利用率,使有限的箔条弹在日渐复杂的空战中能够足以多次应对导弹的袭击。

In the radar passive countermeasure,it is a familiar mode to jam enemy radar by launching chaff cartridge. This paper introduces the theory and process of centroid jamming in detail,and establishes the model of jamming surface to air missile（SAM）,works out the least chaff cartridges that pilot should launch to realize the centroid jamming to the missile,thereby raises the utilization ratio of the chaff catridge, which makes the limited chaff catridges cope with the missile attack many times in more and more complicated aerial combat.
