Abstract:

Atmospheric aerosol and infrared sea and terrain background models are of special importance for the assessment of the performance of electro- optical EO systems. The degradation of the radiance contrast between a target and its natural background, as viewed by an infrared sensor, is determined by the constituents of the intervening atmosphere that absorb and scatter the radiation. The assessment, therefore, depends upon the accuracy of the atmospheric models being used in the propagation prediction codes. The performance of the electro-optical systems is further degraded by turbulence and refractivity effects, causing blurring, scintillation, beam wander, mirages, etc. In thermal imagers, these effects may result in image distortion, contrast reduction and other detection problems.
