MTF Analysis for the Image Performance Prediction of Observation Satellites

The prediction of image performance of an observation satellite necessitates analysis of the performance of a satellite payload and the static/dynamic characteristics of a spacecraft in the space environment. This paper introduces essential performance indices and their systematic relationships required to estimate and analyze image performance of an observation satellite. It also presents techniques and methods of integrated modeling for efficient evaluation of image performance. And the results of a system MTF (modulation transfer function) prediction are given with a consideration of each subsystem MTF of an observation satellite
