Abstract:

The present specifications on flare production are set without any quantitative information on how the various parameters of flare light influence an observers ability to recognize targets. A study was conducted using a Pyrotechnic Terrain Model to examine one of these parameters, flare flicker, and its effect on target recognition. Illumination necessary for recognition at selected frequencies and at one frequency and several levels of modulation imposed upon a steady illumination level were examined. The study concludes that the average illumination required for recognition is not affected significantly by flicker.
