摘要：

The effect of dynamically changing visibility conditions on target acquisition is considered. A model is described that takes as input the statistical characterization of the obscurant and the physical characteristics of the target; the output is the probability of detection as a function of time. Analysis indicates that the variation of the obscurant as a function of time greatly affects the predicted target detection times and, hence, the utility of the infrared system in realistic scenarios.
