EO/IR sensors observing the battlespace environment through the earth's atmosphere can be adversely affected by spatial and temporal variations in atmospheric radiance and transmission along the sensor line of sight (LOS). The physics of stochastic fluctuations is largely understood, and the radiation transport theory and models that include stochastic effects exhibit high fidelity when compared to corresponding sensor measurements. Deterministic structure is not as well understood, however, and the associated radiance levels and variability are often significantly higher than those of the benign, stochastic background. Since the radiance measured by the sensor comes from both the object of interest and the radiating atmosphere and it can also be attenuated by the atmosphere along the optical path, atmospheric structure and clutter affect target acquisition, identification, discrimination, and tracking in ways that are difficult to assess.
