| Abstract | ||
| ABSTRACT A promising approach to the developments of countermeasures against emerging threats such as imaging infrared seekers is to successfully combine obscuration and decoy technologies with modern development capabilities. Carbon black performs well as a perfect obscuring material, but it also has undesirable properties. The experimental studies concern with investigating the thermal screening potential of binary mixtures of calcium carbonate and carbon black to find the possibility of developing an airborne mixtures with the enhanced thermal attenuation and the minimum carbon black percentage. The smoke was generated pneumatically within a designed smoke tunnel equipped with means for measuring the surrounding meteorological parameters such as the ambient temperature, and relative humidity. The thermal obscuring potential of the smoke cloud was tested by using a infrared camera attached to a video recorder and a data processing system. The effect of the smoke cloud on the attenuation of the infrared radiation emitted from a selected target was recorded, analyzed and explained. | ||
