This paper presents an image motion model for airborne three-line-array (TLA) push-broom cameras. Both aircraft velocity and attitude instability are taken into account in modeling motion. Effects of pitch, roll, yaw on analyzed based geometric relations designated coordinate systems. The is mathematically modeled by multiplied exposure time. Quantitative analysis to image motion then conducted simulation experiments. results have shown that caused space invariant while by aircraft more complicated. Pitch,roll all contribute different extents. Pitch dominates the along-track both roll greatly cross-track These provide a valuable base compensation ensure high accuracy imagery aerial photogrammetry.
