Calculating attitude disturbance image motion of one aerial reconnaissance CCD camera

According to the operating principle of one scanning aerial reconnaissance CCD camera, an analysis expression of image motion was derived with collinearity equation, which was about attitude disturbance and image obliquity. Combining the working parameters of imaging obliquity and attitude disturbance, a simulation analysis was given, and the results show that image motion is independent on image obliquity and linearizes relationship of attitude disturbance when image obliquity θ<0.13 rad. Beyond this range, image motion is nonlinear with image obliquity and attitude disturbance. The whole trends will increase coupling with the increase of the disturbance, which can supply a theory basis for the same species of camera and its image motion compensation devices.
