Abstract
How to recognize targets under complicated background of cloud is studied in this paper by stimulating optical correlation. Some factors influencing recognition are calculated, such as the change of shape of cloud, target intensity, clearness or faintness of input image and so on. Simulation results show that targets can be found more easily in cumulus or stratus than in undulance cloud, because undulance cloud is more abrupt change in its intensity. The analyses also show that the clearer the input image is, the more easily the target is recognized;and the more intensive the target is, the more easily it is recognized.
