中文摘要：

特种泡沫云是一种新型多波段无源干扰技术。为提高它对常用厘米波、毫米波等微波导引头的干扰效果，本文分别从理论和实验两个方面研究了气泡液层厚度、气泡半径等气泡结构参数对泡沫云干扰性能的影响，结果表明：气泡半径越小，液层厚度越大，对提高干扰效果越有利，对此可通过调节泡沫云专用施放装置的工作压力或者适当改变所用化学原料的配比来实现。研究结果，对泡沫云干扰技术的发展及其战术运用设计具有重要的价值。

英文摘要：

Special Foam Cloud （SFC） is a new tool for multi - bands passive interference. In order to improve its interference effect against micro - wave Guidance, the interference theory of SFC was discussed firstly, and the interference experiments of SFC were studied with the special integrated testing system of guided missile, then the relationship between the bubble＇s structural parameters （the bubble＇s radiuses, the liquid layer＇s thickness, etc） and the interference effect of SFC was obtained. The results indicate that the smaller the bubble＇s diameter is and the thicker the bubble＇s liquid layer is, the better the interference effect is. And those are easily realized by adjusting the operation pressure of the equipment to discharge SFC, or by changing the material formulations of SFC. These conclusions are helpful to improve the technology of SFC, and with tactical value for the design of SFC.
