dc.description.abstract In recent remote sensing researches, one of the essential techniques is how to estimate the current and future status of satellite on the orbit. Integrated Ray Tracing (IRT) method, what we report in this paper, has been developed as the state-of-art end-to-end simulation technique. We focus on the IRT technique for the Geostationary Ocean Color Imager (GOCI) which was launched on June 2010. IRT simulation technique deals with 3D modeling of GOCI flight model as well as the entire space environments among the Sun, the Earth, and the GOCI. Trial simulation runs for the GOCI imaging performance were focused on the combined slot images and MTF. First, we investigated GOCI in-orbit MTF performance with the slanted knife edge method applied to an East coastline image of the Korea peninsula covering 38.04N, 128.40E to 38.01N, 128.43E. The ray tracing simulation results showed 0.34 in MTF mean for near IR band image while the GOCI image obtained 9th Sep, 2010 and 15th Sep, 2010, were used to produce 0.34 at Nyquist frequency in MTF. Second, stray-light effect from unwanted reflected bright source for GOCI is estimated in the realistic simulation. With integrated ray tracing technique, we estimated how much the stray light according to the targets suggested clouds affects near-by slot image. Two ways including East-West and North-South effect were progressed at each slot. In addition, the spectrale state-of-art end-to-end simulation technique.
