Paper Abstract

This paper is concerned with the measurement of the Optical Transfer Function (OTF) of earth orbiting imaging sensors, from typical operational imagery. Historically, the OTF of aerial systems has been obtained from special targets, such as artificial edges (Ref. 1) or lines (Ref. 2), or their naturally occurring counterparts in the form of coastlines, field boundaries, etc. The OTF, T(f), can then be obtained directly from the Fourier spectrum, I(f), of the image by the imaging equation,
