ABSTRACT:
Method for measuring the camouflaging capacity of a smoke. A selected radiation source, such as an IR radiation source, is divided into a predetermined number of IR radiating elements having mutually differing radiation temperatures. After the release of smoke between the radiating elements and an IR camera, the number of temperature peaks which cannot be distinguished with respect to the background temperature is employed as a measure of the IR camouflaging capacity of the smoke. When measuring the camouflaging capacity of the smoke over a wide area several groups of such IR-radiating elements are distributed over the area.
