| ABSTRACT The advent of imaging seekers in the range of (8-12) μm band poses a new challenge in the area of infrared countermeasures. The application of camouflaging tent in this field is one of the effective methods which are used to decrease the thermal signature of the targets and hot bodies in the field. In this paper a white duck textile barrier treated with white emulsion paint, aluminum metal in different forms was used to reduce the thermal image of hot plate (100 oC). The effect of aluminum powder, aluminum spray, and aluminum foil on the reduction of the thermal image was studied. The results show that, as the aluminum powder content increase from 4.2 to 8.37 mg/cm2 the reduction in thermal image decreases from 90% to 87.3%. However, for aluminum spray, as the areal density increases from 3.7 mg/cm2 to 11.1 mg/cm2 the percent reduction increases from 84% to 90%. In addition to that, the application of a stream of air with volumetric flow rate of 1.2 lit/s between two identical samples improves this percent to 98.4%. The results also show that, aluminum foil supported on white duck textile has the greatest effect, where it gives 99.7% percent reduction in the thermal image. | ||||
