Abstract
A survey of the infrared radiation characteristics of representative Arctic targets and backgrounds was conducted at Resolute Bay, NWT, in May 1972. Thermograms of buildings, vehicles, fuel storage areas, humans and animals were recorded at 3-5m and 8-13m against snow. Thermal contrast degradation with range in ice fog was investigated on one occasion. Several materials that could be carried in an aircraft also were deployed on snow to evaluate their potential as thermal sources that would draw the attention of a sensor observer during search operations. The results of the survey show that the apparent snow background temperature in May under daylight conditions is relatively uniform over wide areas. Targets such as buildings, vehicles, fuel tanks, humans, dogs, etc., offer contrast to snow of several degrees. Thermal imagers (FLIR, IRLS) should be useful tools for airborne surveillance, reconnaissance, and search in the Arctic during the winter season.
