Title  Development of foam shielding device

Abstract

Foam has been found as the potential multiple-band passive photo-electricity countermeasures(PPECM) recently. By theoretical research and experiment analysis, the author designed and builded foam shielding device. The author learned the foam effects evaluation methods, and gained formula of better foam effects by doing the evaluation of different foam agents using simple pour method. Using IR thermal imager, the author gained IR radiation attenuation effect pictures of high temperature surface, which proved that foam has good IR attenuation. Some suggestions were also presented for further research.
