Abstract

We present an end-to-end modulation transfer function (MTF) simulator for high-resolution spaceborne imagers. The simulator comprises the modules of atmosphere, optics, detector, and satellite. The mathematical background of the modules is developed in a python environment. Each module computes modulation transfer function for the associated input system parameters. The resulting MTF of the system is the convolution of each module and provides system level performance. The MTF tool is validated for a hypothetical high-resolution electro-optic imager.
