摘　　要：在对导弹导引头测向系统的诸多干扰方法中,闪烁干扰是一种普遍认为较有效的干扰。闪烁干扰的效果在很大的程度上取决于发射源之间的距离和闪烁频率。本文给出一种评估闪烁干扰效果的新的准则———方差期望比最小准则,根据此准则给出双机闪烁干扰的最优距离计算方法。Among the methods of jamming the direction - finding system of the guide head of a missile, twinkle jamming is generally considered a kind of rather available method. To a great extent, the effect of twinkle jamming lies in the distance between the emission sources and the twinkle frequency. This paper presents a new rule to evaluate the jamming effectiveness - least variance - to - expectation ratio rule. And based on this rule optimization algorithm of twinkle jamming by two planes is elucidated.
