Abstract

The Target Contrast Characterizer (TCC) was described in detail by the authors last year in the Proceedings of SPIE Vol. 926. It consists of experimental equipment and methodology which permit images of near-field (or close up) and far-field (or at engagement range) targets and their backgrounds to be registered in near real-time for characterizing the effects of the atmosphere on inherent and propagated target contrast. This paper details the method for obtaining target contrast transmission measurements using the TCC. Measurements of target contrast transmission are compared with model predictions of atmospheric transmission. In addition, the very sensitive measure of pixel-to-pixel or area-to-area contrast transmission obtained with the TCC is discussed as well as improvements which should be added to optimize near-field/far-field image comparisons.
