Methods for simulating infrared remote sensing images based on scene models

In order to make cost-versus-quality of launched satellite trade-offs, computer technology can be used to simulate the physical process of infrared imaging from land surface to archiving images before launching satellite. The available simulating methods are not able to simulate big-footprint scene and complicated land cover types by using thermal radiation transfer models and imaging physical models. Due to this reason, we selected a scene model to setup simulation system which composed land surface scene, atmospheric effect scene and sensor imaging scene. In this study, all kinds of relevant methodology about simulation utilizing scene models were analysed, a proposal of thermal infrared remote sensing simulating system was suggested which could be used to simulate wide area scene and different land cover types. This work is a new approach for infrared imaging simulation and it is helpful for relevant researching works.
