In this research, we are interested in applying the model to simulate the radiative transfer through the atmosphere under realistic conditions for assessing the significance of the effects of the atmosphere and conditions on shooting satellite images. The main objective of this application is the analysis of satellite measurements, along with their variations atmospheric parameters. The purpose of modeling is to understand how different components of the measurement system combine to make a measurement. The form and content of a model depends on their purpose. The model is constructed to describe and characterize the measurement system to understand the phenomena which he is registered and to predict their behavior under the effect of an external action or as a result of a partial modification of the system itself same. The model developed is to break the middle-ground atmosphere into subsets in interaction with the solar spectrum and the sensor onboard the satellite. The proposed radiometric correction method is simple because it is based on pixels that are known to support their radiometric images. The luminances are simulated using the software (SDDS) which allows us to establish rules between reported digital luminance and luminance reflectance. Resume - Dans cette recherche, nous nous interessons a l'application du modele pour simuler le transfert radiatif dans l'atmosphere dans des conditions realistes pour evaluer l'importance des effets de l'atmosphere et les conditions de la prise des images satellitaires. L'objectif principal de cette application est l'analyse des mesures par satellite, ainsi que la variation des parametres atmospheriques. Le but de la modelisation est de comprendre comment les differentes composantes du systeme de mesure se combinent pour faire une mesure. La forme et le contenu d'un modele depend de leur but. Le modele est construit pour decrire et caracteriser le systeme de mesure pour la comprehension des phenomenes pour les quel il a ete enregistree et de predire leur comportement sous l'effet d'une action exterieure ou a la suite d'une modification partielle du systeme soi meme. Le modele developpe est de briser l'atmosphere moyenne en sous-ensembles en interaction avec le spectre solaire et le capteur a bord du satellite. La methode de correction radiometrique proposee est simple parce qu'elle est basee sur les pixels qui sont connus pour soutenir leurs images radiometriques. Les luminances sont simulees a l'aide du logiciel (NSDD), qui nous permet d'etablir des regles entre luminescence numerique et luminescence de reflectance.
