This paper examines the measurement of MTF of slant edge targets from airborne imagery. The MTF is calculated by extracting the edge spread function from the slant edge, deriving the line spread function, the performing an FFT to get the MTF. Because characteristics of airborne imagery are not controlled, using edge targets to get the system level MTF present challenges. A method to calculate the MTF from edge targets in airborne imagery is proposed by normalizing the scan lines in the edge spread function and low pass filtering it. An example using air borne imagery is shown and compared with analytical results and laboratory measurements. The paper also examines extracting the effects on the MTF due to image blur from jitter common with air borne imagery.
