Image based analysis of atmosphere turbulence effect on the target detection

The performance of EO/IR systems is influenced on the testing circumstance. After studying theoretically the performance variations by environmental conditions, we estimate the practical performances of the systems. But the results of test in the field is beyond theoretical estimations due to sudden changes of the atmospheric conditions which becomes worse under low altitude and long distance between targets. So in this paper, we show distortions of target signatures by atmosphere turbulence using images from the field test for target detection, and also shows linear relations between the target detection rates and its theoretical expectations.
