We present the optical transfer function (OTF) analysis of a spaceborne imaging sensor. This includes the effects of detector footprint, diffusion, smear, jitter, sampling, and time delay and integration. Each effect is analyzed under various design choices one of which corresponds to our designed complementary metal-oxide semiconductor imaging sensor. Effect of each subsystem is separately demonstrated using OTF values and corresponding degradation on a test image.
