Abstract : A method is proposed to measure the effectiveness of different types of flares in terms of night vision performance. Eyeball, image intensifier, and image converter performance models have been developed at the Night Vision Laboratory and are the basic tools in this evaluation. Validation of the performance models was accomplished by conducting a terrain model test simulating the nocturnal use of pyrotechnics. Sample analyses utilizing the proposed measure of effectiveness are illustrated for alternative types of flare intensity configurations including the standard, increment, and Neopolitan flares. A description and performance predictions of the covert flare are included. (Author)
